Totally unrelated, but just a thought that I wanted to throw into the room
before it vanishes, maybe someone will remember it when WC 2.0 is being
designed :-) Just ignore me...

Instead of having a number, why not have two list of features that the
working-copy creating client defines and which say which SVN features need
and should be support by other clients. For example, something like this:

NEED: gravity air
WANT: world-peace

So another SVN client reads that list and says "I can support 'gravity' but
not 'air', so I may not touch the WC". Another client says "I can support
both 'gravity' and 'air' but not 'world-peace'; since that's not critical I
may touch the WC".

That would allow to add new improvements and also tell the world about it
without necessarily denying access for older/different
clients/implementations.

Just a thought :-)
