I don't think there is a general rule.  As long as the change is trivial
I keep them personally, otherwise I drop them.

E.g. if you just remove a few hunk because of new code that isn't
present now I'd keep them, if there are more complex changes to the code
flow I would consider dropping them.

That actually is pretty nice, as it allows people to migrate over
(not that I've heard of a whole lot of usage of sedutil, but being
compatible to some extent is always nice)
