Agreed. But mod_dav_svn is not going away. Maybe we do not add new
features to it, but we have to maintain it. So the code has to live
on and cannot really even be cleaned up. Does putting new code in a
new library make that much difference? Can't the new code just live
in new .c files and be built into the same library for deployment? I
have two goals in suggesting this option:
1) Eliminate the need for 2 URL's. This is bad. With your Google
code hosting do you really want to offer 2 URL's for all repositories?
I am sure we do not want to do that at CollabNet and I doubt
SourceForge and other sites want to either.
2) We do not have do a new implementation of DAV autoversioning.
