Well... It's a normal occurrence in most projects. Maybe not in Emacs, 
but what about GCC and the rest, which also use 'make tags'?

Also, the developer might be developing some new feature on a branch 
(adding new files), and switch back and forth between branches, 
effectively deleting and recreating said files.

It would be nice to keep the index up-to-date automatically during all 
that. Many users would expect that, I think.
