No. I want to build high level tools not keep on working on the
pysvn and workbench keep me busy enough.

I'm frustrated by the lack of features and outstanding bugs in
svn_client API. I'm seriously investigating
what it will take to avoid it completely and work with RA and WC
instead. I know that this will fix a number
of the issues I have with svn_client API.

The reason I see for the repos root is to be able to turn the
changed_paths into URLs, otherwise you have cannot use the
info from a log except by guessing.
