Every now and again in these games some QoL thing does get accelerated. I believe for Umamusume, we are getting one in that Champ Meet Finals will hard set Mood to Great instead of randomized like it was on release. (It got changed to fixed Great later)

For everything else, I actually can totally understand how or why things don't get accelerated. It's one thing to just deploy from your repo the incremental set of check-ins up to a certain point. It's another thing to pick one specific file and fast forward it only, god forbid it has Some Dependency that also needs to get updated that you miss or has Good Reasons to not get fixed by itself.
