Refactorings are seldom done in isolation. It's almost always part of a larger 
change, either a bugfix or a new feature/capability that prompted that. In 
ideal cases, the refactoring is done ahead of the new feature or expansion of 
the capability, so it could be picked back.

But then the rest of the change is probably going to change the code anyway 
and obviate the benefit we'd get on having the refactor picked back. We would 
end up with code changed for the sake of change, in a configuration that was 
never tested in newer branches. At best, it's a no-op; at worst, we did miss 
something that introduces a regression.

So I agree with Ville: it's not-always.
