Nobody's probably thought this through, but if I had to guess, the first revision to the rule will be "no _assets_ generated with gen AI" because the most upset parties about gen AI use in gamedev are asset creatives who create textures, models, and audio, perform music and voice acting, etc.

Upscaling technologies are transformative but post-processing. The uproar isn't over what happens in the render pipeline but in the creative process.

Same reason why auto-LoD generation wouldn't and hasn't pissed anyone off: it's not generating LoDs of a mesh that's problematic, it's generating the source model that an artist would create.
