This mostly stems from the fact that allows for omission of the
cRLDistributionPoints (Item b), but requires OCSP (Item c), unless the
server supports stapling. requires the cRLDistributionPoints for sub-CAs (which can _also_ be
server certificates, since we don't restrict the subjectAltName on such
certificates), but also allows (strangely) the omission of OCSP for
stapling (I suppose it's presuming OCSP multi-staple)?

Happy to take a stab at correcting both of these via Ballot, since I
suspect the logical intent, as reflected in your question, is that:

1) CRLs MUST always be present on intermediates
2) OCSP MUST always be present on intermediates (or are we really
advocating for the terribad multi-staple?)
3) CRLs MAY be present on end-entity certificates
4) OCSP MUST be present on end-entity certificates, unless the server
supports stapling
5) CRLs and OCSP responses MUST return the same revocation status
information (presumably, either in Section 2.1 or Section 4.10.1 / 4.10.2)
