Yes.

Yes, it violates a MUST. That doesn't mean that building such a crawler is 
a bad thing. Lots of us violate specifications in the privacy of our own 
organizations to achieve some purpose or other. Debugging is a classic case 
where we retain things that specifications say should not be cached, etc. 
But yes, I don't think it conforms to the RFC 3986 and friends 
specification for the dereference of an https-scheme URI. In your example, 
if I understand it, this is being done to answer a question about the state 
of the Web itself (what's deployed with weak encryption etc.)

The situation with ISPs violating the specification to me seems very 
differnt in spirit. ISPs are doing this specifically to interfere with the 
contract between users and resource providers, in exactly the situation the 
specification was written to address.
