Personally, I would like more advanced svn admin commands than just
svndumpfilter to modify a repository.

For example, a user "cp file1 file2" and "svn add file2" instead of
"svn cp r HEAD file1 file2". The copy history is not preserved in
the repository, but really, it should be. I know modifying a
repository sort of goes against the whole version control and version
history scheme, but there are cases where the repository itself is
inaccurate and it should be able to be fixed "behind the scenes".

Another example, when I "svn mv" or "svn cp" I sometimes forget r
HEAD to specify the revision to move/copy from. When I forget, the
commit uses the head revision of the repository instead of the head
revision of the source file. I would like to correct this number in
the repository, again to correct inaccuracies in the history.

P.S. Personal opinion!
