the point isn't hard to see or some wild stretch at all. the same way that they shortened sequences in the anime so far to expand on other stuff, they're likely going to continue to do again - and with gege being upfront about culling games whiffing, its very likely to be what ends up being altered.Still don't get what your point is, you think Mappa is gonna run more episodes than two cours for Culling Games? Less episodes? I don't see them making any JJK arc shorter than 24 episodes, they are gonna milk it as much as possible.
The main reason I don't see them being ridiculously greedy and making GC even longer than 2 cours is because Culling Games has no resolution and there's no "ending" point for a season 3 except for Sukuna taking Megumi's body or Gojo coming back.
for example - literally no one anywhere argued for shortening sukuna screen time to make sure that mechamaru got his full time allotted
if gege wasn't serious about it, why would mappa be? especially with how they've taken winning liberties already? they can put that time into a whole non-canon movie instead lol
