That's going pretty far out on a limb (hah!) to create some artificial relevance given the context. Meanwhile LLMs are easily relevant in almost every way that matters to programming languages, more than even IDEs.
That doesn’t limit formation of a subcommittee to concentrate their discussion for the health of the group. Any topic is eligible based on group impact regardless of its perceived breadth by those avidly discussing it.
Subcommittees/subgroups are perfectly fine of course. But, again, given the context, this isn't that case. This is a core person in the ecosystem making a strong suggestion about how general groups should operate. Doesn't take much imagination to see things get to a point where only groups that seriously discourage or outright ban anything re LLMs are considered "legitimate". It's their prerogative of course but... lol.
