I still believe it should be configurable.

A root CA can be revoked for a number of reasons although key compromise has
security issues if the responder certificate is part of the chain (i.e. cases #1
and #2 in that message).

Apache OCSP AFAIK currently doesn't handle case #3 at all (trusting responders
with keys trusted by some out of band means).

There is a fix/enhancement for this (which also addresses the issue Steve
Marquess brought up) in PR46037.
