Alright, this boils down to misconceptions, and a lot of it. My first course of action is to address the staff complaints you listed above:
1. There was a mutual understanding at the end of it.
2. Arrow explained some backend dev stuff and the complaint eventually dropped.
3. There was some changes that occured.
4. Misconception. It was clarified and dropped.
5. The drama was investigated. Investigations tend to happen behind the scenes out of the server's eye.
6. Skull apologized after discussion in the post.
7. Matt was apprehended by Garn about this.
Now onto individual topics I will refrain from posting on a perspective of how the development team handles administrator maintainers outside of what I was told.
These were mostly instances that were never reported. But there was some back end investigations that occurred. Inter staff discussion are not typically seen until said person is literally removed. Nanako was stripped of dev perms after abusing them. To be all honest, I do not know what personally exactly happened to Fowl and Pacman, but they either got removed or pressed out by the dev team.
From what I've personally seen with access to the inter-staff discord, this is incorrect, because they do keep tabs into the moderation chat and we do have discussions.
Alb is a maintainer. They have access to the server. Garn also has access but generally uses it when the server dies and he's around to hit the big restart button. I've seen Skull make mistakes, but he hasn't ever tried to cease the server. I've never faced disrespect from him and when I've seen it, it generally ended in an apology (I.E, that staff complaint 6)
This is a contradiction of your point above. To be a maintainer, you have some server access. You want administration to have control. You don't want administration to have any control. That's what the maintainer position is from what I see: To have some control in the server operations and code base.
There are clear guidelines staff follow. This is why I'm posting this, because it peeves me when people have a misconception that staff are immune. Staff, generally to get their position, show that they uphold the general server rules. That's why you don't see them getting banned because Aurora gets as a whole gets staff from people who show they understand the rules, can learn from their mistakes, and be all around decent people to work with. In fact, I've personally talked to skull about one of his frustrations being vented into OOC and moderated it like I would do any other player by asking one of the admins to disable OOC. Then I spoke with him a little.
This is why staff complaints exist for staff members, not involved, to take an unbiased approach on the situation and come to final decision if said staff member was in the right or wrong.
While I can't post some examples onto other people, I can post my own mistakes and issues that were investigated and resolved like any other person. I will be blurring the names of the people who issued my notes since it's pretty standard when sharing them.

During my time as a moderator.
The staff team does moderate itself. I've spoken with people. I've started conversations. I've been personally spoken to before when I screw up. I understand the misconception that staff are immune from an outsiders perspective, but most of the issues, are handled in the back end. 90 percent of them get resolved internally and it never comes to the light of day since there is honestly no place for it. It functions. It exists. The mere exsistance of the entire staff team being 53 people and functional is evidence enough of this fact. Because if there was not moderation, there would not be a team that exists since it keeps the team functioning and working together despite the MANY differences among everyone.
Look at the two recent lore arcs for example involving Tajaran and Skrell. You have lore developing a concept. Developers actually adding the concept into the game. CCIA pushing the IC company side of things. Administration enforcing the rules so it doesn't fall into a mess.
All of this is not possible when a team is dysfunctional. Inner staff moderation is a key corner stone in a functional team.
