"Refactoring" might have devolved into that now, but I don't think
that's what Fowler was pushing.

To be pedantic, refactoring doesn't assume that, that's how it is
defined.  If you're changing the external behaviour then it isn't
refactoring that you're doing.  It's nice that Fowler named the
process, and showed some of the different refactorings possible, but
it'd be nice to be careful of what we use that word to describe.
