Agreed, we should go ahead and make the changes. People who use our
code for plugins are already going to have a boat-load of stuff to
change in each major release, and doing this isn't going to add a lot of
burden, and it will give us cleaner code for the future.

If we had not made massive cleanup changes years ago, our code would not
be as good as it is today. By avoiding cleanup to reduce the burden on
people who use our code, we are positioning our code on a slow decline
in clarity.

What I don't want to do is get into a mode where every code cleanup has
to be verified that it isn't going to excessively burden outside code
users. Cleanup is hard enough, and adding another check to that process
makes cleanup even less likely.
