Why don't we do this:

a.) immediately stop sending UUIDs on update. I *think* the liveprop
    entries are okay. Are they?
b.) in the same atomic change, start sending an "X-SVN-Repository-UUID: "
    header, and modify ra_dav to handle this.
c.) do (1)
d.) do (3)
e.) wait until most clients are updated. I think, at a minimum, this means
    binary packages available for most OSen + one more month. There's really
    no forcing function on this.
f.) revert (a)

Thoughts?
