To have the functionality today means I have to invest more time on
these discussions about which hackish or painfully inefficient way to
implement it, and for no real gain (because of the lack of better
deltification). Not to mention that the functionality will likely
have to be rewritten later to make use of whatever deltification
improvements come along in the future.
To re-add this functionality *later* when it will actually be useful
costs nothing today (except a quick edit to comment out the
functionality in svnadmin).
I am *seriously* not trying to get out of doing work here -- if there
was a Good way to accomplish this task today, I'd be all over it. But
there really isn't a good way to do it Right (that I've seen proposed
so far).
I just want someone to tell me that they need `svnadmin deltify'
today, 'cause I have a feeling nobody but me has ever even used it.
