The software won't see any difference except it will provide a sanity
check when we're developing and modifying Subversion code and testing
against new WCs.  I don't think there is any need to upgrade existing
development WCs in this respect.

I'll mention it in a comment in the format 99 step, but don't think we
need to write any SQL for it.
