I think its mostly valuable to cause less confusion of new people, and
though it is a simpler thing every little thing can be the thing that
breaks the cammel's back.  Yes its not all that hard to configure
editors and what not to handle it properly, but every new person needs
to do it, and looking up configuration options takes time that can more
profitably be spent.

That said keeping backports as easy as possible is also certainly
important.  I'm curious why renames hurt doing backports, I'm pretty
confident git cherry-pick will handle it for you, and if you like patch
files for some reason I'd think its easy to fix up with sed though
running that for each backport by hand would get a little old.
