As a result we are declining this Idea. While declined the Idea can still be voted, and commented, upon.

Firstly, it is well worth considering OCSP as an alternative to CRLs because it only sends small responses. A CRL contains the list of all certificates ever revoked by a CA, which is why they tend to become large enough to cause performance problems over time. By contrast, OCSP only contains the revocation status for the requested certificate.
Secondly, it's worth considering solutions such as JMS session pooling and conversation sharing as a means of prolonging the connection lifespan and avoiding duplicate handshakes. Arguably an MQ application which repeatedly connects and disconnects has not been very well designed.
On many platforms, there is already some level of caching for CRLs retrieved from an LDAP server (though not via HTTP, or when the CRL is indicated via CDP certificate extensions). Extending this to HTTP and making the cache timings more configurable is something we would consider for the future.
