Rollback isn't a special flag, letting inactive users keep it doesn't do any sort of harm. The only reason it's not given to everyone universally is cause the quick 1-click, no reason, multiple-edit reverts can be used irresponsibly by casual users. It's not really something you lose by going inactive.

Removing rights of piles of users is actually a huge hassle. There's no way to do it in bulk, so for each user you have to go to their user rights page, either by first visiting their contributions or by manually typing their name into the special page, tweak the rights, type/paste a reason, then submit. With the lack of downsides for leaving rollback on a user regular bulk removal of rights from a pile of users is actually a pretty heavy burden to add to sysops.

((Protip, the row added to the logging table to log changes to a user's rights is larger than the user_groups row removed to take the rights away. ;) So ironically when you remove a right you just make the database larger, not smaller))

Now then, I have to finish a tiny bit of work and then get to sleep so I can go to Anime Evolution's J-Fest mini-convention that starts in 9.5 hours.
