That's good - I'm glad to hear this.

I can accept a performance hit for not upgrading. This backwards
compatibility is important to me. I realize svn is not cvs, however cvs
has been around for quite a while. And, I don't think it has seen too
many changes to the file format over the years (RCS files right?). This
means I can recover old cvs repos from backups and almost always just
drop them into a current system and use them again. That's very powerful
(and comforting).

Either way, you can bet I'll be adding an svnadmin dump to my backup
process once (if?) I get these recovered.
