Personally, I've found myself getting lazier recently, trying to get a single session to handle tasks that should be broken into multiple sessions, etc. I've suspected claims of nerfing might come from changes in user behavior. I'm glad more disciplined checks are being run.
User behavior is overwhelmingly the most likely reason, regardless of what the text above your reply says.
It could be harness changes too, been quite unhappy with opus 5.5 the last few days and there have been a lot of harness updates.
