Well, there still is some risk of introducing real bugs this way (I *have* seen
"trivial cleanups" that broke things) and is it really worth it?

Besides, old code is somewhat like an ancient building. Yes, it needs to be
kept in a good shape, but you won't replace bricks in it just because they are
old, will you?
