What's the problem with interpolations?

A long, long time ago, when "hg push" didn't fall back to "default" when
"default-push" wasn't set, a trick that was often recommended was to put
something like this in ~/.hgrc:

[paths]
default-push = %(default)s

Sure, that's not needed anymore, but somebody (Thomas?) even added some
code to ui.py to make sure this kind of thing worked.

I don't think interpolations are an essencial feature, but I'd be
surprised if there's nobody out there using them.
