I'd urge you to to lock the old repository, build a new subversion
repository using "svnadmin dump", "svndumpfilter", and "svnadmin
load". Then switch your users to the new repository. Thatwill make
clear to your clients that are, in fact, using a different repository
with a different history and avoid confusion. Subversion is *very
picky* about deleting history, and there are philosophical and
security reasons to hinder the alteration of history as you are
looking for.

It sounds like you really want the "obliterate" feature to delete
accidentally committed sensitive files, which has never been
successfully done.

Why are you using "--incremental" ?

The way you fix this is to *not use any* existing working copies. Make
people check out a new copy with the new uuid. You have zero control
over whether a working copy has those deleted revisisions.

I went through this with a bad commit in a source tree for a stock
exchange, and the cleanup when I failed to switch repos wasn't pretty.
