It could be argued that this is still a useful feature. The repository could
be held in a secure location whereas working copies aren't. Consider road
warrior type users for one example.

The problem is that it isn't just the version system that potentially creates
copies of private data. Compilers, editors and desktop search tools all will
do so too and create these files all over the place. The two sensible
solutions do not include updating subversion. Either the OS should
automatically shred files that are deleted or an encrypted filesystem/disk
should be used (with shredding enabled).
