I'm concerned that we have always to consider two cases of SSL usage in the
source code : with or without server certificate, along with corresponding
cases in clients.

If we could make it easy to the repo administrator to start using SSL with
certificates, it will help security, even if it's not as automatic as in your
proposal. For instance, "svnadmin create" can automatically make a
self-signed certificate that is placed in the repo config directory. These
pre-made certificates can now be used by svnserve. Granted, most client users
will just accept this certificate, and not verify the certificate
fingerprint. The repo administrators that care about this, will have made
their certificate fingerprint available out-of-band, even if it's just
posting the fingerprint on a html page.
