As it was already mentinoned here: http://www.ietf.org/mail-archive/web/pkix/current/msg04489.html I would no longer get a popup from my OCSP client that tells my that I'm unauthorized to submit OCSPRequests to that server, and that the server has been moved to a blacklist, and that I will have to manually enable this server after obtaining proper authorization before my client will send any further requests that OCSP server. No longer being interactively bothered about this error seems like a very valuable improvement! -Martin
