Agree with Carver here.
Any serious discussion realistically, would be on the forums anyway because it's an environment built to take your time and type out a well-thought out response.
Discord, however, is just a typing speed competition, and whoever gets the first word is going to segway into whatever.
Forums have topics and titles, with the first post being basically a coherent anchoring point. The channel you just proposed is just grabbing at straws at whatever people "feel" at the moment.
And you know, feelings are terrible for coherent discourse. If people aren't discussing what you want to discuss, you're shit out of luck unless you want to derail the current conversation.
Additionally : The fact we are discussing this *RIGHT HERE* throws a wrench in your entire argument.
For the arguments that code_dungeon and lore_channel are existing "serious" channels is misguided.
Most, if not all developer discussion occurs on the GitHub, and to a lesser extent, the developer discord. code_dungeon is just an extension of the developer discord, albeit more public.
And I'd reckon the same argument for lore_channel is likely to apply as well - we have entire, separate discords for human, skrell, IPC, etc. lore.
No matter how idealistic your idea of this channel's going to be, I'm pretty sure this is going to de-evolve into political-thunderdome 2, electric boogaloo.
And the argument that the "mods and admins will handle it" is also idealistic, because the very same admins and mods participate in political discussion as well.
