Yeah, I think that is true, but trying to assert this would mean much more strict review than we currently have (at least in nixpkgs, I look at nix far less). You say so yourself - people don’t like nitpicking, and a lot of the quality gates here will feel like nitpicks.
If more senior contributors start adopting LLMs as well, or buckle under the increased load, I seriously doubt there will be capacity for this. There already isn’t sufficient capacity for just human submissions.
Anecdotally, even heavy contributors seem to have issues with this - I think here is an example of someone being happy enough to be done with the work to not consider the why very much, only being caught because it happened to go to discourse: [RFC] Nix function that overrides a scope, with automatic inheritance propagation
Arguably this is an example of the happy path, and my entire argument is very slippery slope, but there is plenty of evidence of other communities (especially commercial companies) slipping down that slope.
