I much prefer Glorsh as something we, as human readers partaking in fiction, shouldn't understand. We (the IRL humans reading) do not need to know why Glorsh did things to make things fun. The fact that we don't know exactly why is one of the most compelling parts about Glorsh, and the fact that a new Glorsh could be one slip up away gave credible reason to distrust synthetic lifeforms. No one likes dealing with the idiot human that says the toasters are stealing his jobs. It's discrimination based on smoke and mirrors almost, it's conflict but it's not nearly as fun as having to deal with this ancient Skrell that has very real reasons to distrust machines.
It was a unique lore take that provide a point of conflict, and I'll be very disappointed if we lose it.
Additionally, psionics should most definitely stay in the "The average skrell has mind reading and thats about all the fun." I'm cool with like super talented skrell having better and more advanced powers, but they should be few and far between, and also heavily regulated by the Federation.
I DO like the increase in human contact though, that's pretty good.

also big time agree with Chada, the reason Skrell have concerns about Diona is because of Glorsh.
