I agree with you that it's best to return false negatives instead of false positives as the latter can create issues. I will add the subject to the equals test, at least that will cover some cases, but want be a complete fix. Do you have a suggestion for fanout, xml, headers etc ?
I wouldn't treat those as special cases. From the perspective of a producer my-fanout/subject1 and my-fanout/subject2 are still not equivalent, even though the exchange type does not do any subject based filtering, as the message they will produce by default will differ.
That difference is potentially even more significant for xml and headers exchanges.
As you say, false negatives are to probably be preferred, so any two destinations including a subject where that subject does not match can in my view safely be viewed as not equivalent.
