I think that the main problem is that Subversion keeps all it's
knowledge inside the folders you are deleting and moving etc. -- so
you are essentially lobotimizing it and then asking it to grow a new
brain automatically.

I'm pretty sure there is an issue already filed about making
Subversion keep it's knowledge somewhere else rather than inside the
working copy so that shuffling and deleting folders won't be such a
problem. I believe someone did work on it for a while and was making
progress, but they dropped it as far as I know.

If you are interested enough you could research that issue and
followup on it with the design and details on how it would work and
post it to the dev list and then maybe someone will pick it up and
work on it.
