I believe there is nothing prohibiting MKBs to be published. However, to save space, here's the host revocation list for MKBv61:
Code:

Just check certificate ID and you'll see if it is revoked or not. Note that host private keys aren't particularly interesting, they can be easily extracted. The one I've posted some time ago on this forum still works up to MKBv61 (MKBv62 was released since then, but I don't know if it was revoked there or not).
