Oh, I wouldn't assume that so-and-so's flame was the reason others
didn't answer your original question :-). More likely no one had a
good answer to give, so they didn't respond. That's a normal pattern,
and doesn't much correlate with the presence or absence of a flame in
the thread.

There's certainly no chance of revisiting it for 1.0.0 or any of the
1.0.x series. Personally, I would also not want to revisit it for
1.1.x, since I think there are more important improvements to be made
there.

I like (a), and for (1), you could have your post-revprop-change hook
write out a log of just the metadata changes -- make up some simple
XML format -- to be transported with the incremental dumpfile. (If
you do this, and you have time to package up the scripts in some
reasonably comprehensible way, we'd love to include them in the
contrib/ section of Subversion!)
And yes, I agree this is a kluge. It's just a question of priorities.

I think (a) is your best bet. I've never tried (b), but anyway a
method that keeps the data in human-readable/human-hackable form seems
somehow more appealing.
