It might also be an option to remove AUTOMATIC_USE; clients that want a certificate applied to all requests generate the extra frame for each stream, but that's fairly small overhead.

I think for legacy reasons, it makes sense to restrict sending USE_CERTIFICATE 0-1 times *unless* the server sends multiple CERTIFICATE_REQUIRED messages.  This support was added to parallel TLS 1.3, which permits multiple simultaneous demands for (presumably different) certificates.

I think it is more multiple certificates that causes problems here than AUTOMATIC_USE.

(AUTOMATIC_USE has its problems, but those seem to be mostly related to the server becoming confused about what the client actually meant).
