Hold it there: why is renaming a file "trivial"? It's not: every reference
to that file, anywhere in that software, may have to be changed with it.
That means there are associated changes with the renaming, which the
Subversion tracking may not be able to handle gracefully: that's especially
true with source files.

I agree it could be better, but if you really think about what is associated
with it, you start to see why it does it this way, as a "duplicate", then a

That's why you use your own branch! Getting "outstanding edits" preserved is
a huge problem: The subversion "use your own darn branch!" approach is
supportable, in a way that "force outstanding checkouts to be updated from
here" would become nearly impossible to manage. (I've had to deal with that
approach, under CVS and Perforce: it's painful.)
