Perhaps, but consider my desire to push out incrementals to not just
one but very large numbers of users. (Say, for example, that a huge
open source project used SVN and wanted to allow thousands of
organizations to keep read-only repository mirrors.) You might not
want to give each and every one of them a 3G full dump every night if
you can avoid it -- flood filling just the incrementals, if it could
keep everyone up to date, would be far superior.

I have to say, though, that even for backup purposes, I don't like the
subtlety of "incrementals aren't really incrementals". Some users will
miss that fact and get screwed one day, without knowing it because
they won't think to check all the log messages etc.

It seems less general -- and like more of a pain. It also can't easily
accommodate my dream system in which huge numbers of people are
maintaining local read only copies.
