That particular ban has an interesting backstory of bureaucratic
decisions that seem misguided in retrospect.
The problem is that the information in OCSP requests is potentially
very valuable to an attacker who lacks the ability to fully wiretap
the connections between the OCSP client and the ultimate source of
the checked certificate.
