I've expanded the dpkg man page section on --compare-versions as

I've spend an hour or two before figuring out, that it was the weird '<' '>'
semantics that is "broken". So I'd be glad if you could include more
explicit documentation of the problem and spare others wasting their time
debuging the fallout of these particular semantics.
Right, I'm marking '<' and '>' as deprecated there, and making the code
issue a warning in the same way the control file parser is doing.
I don't think the rest of the operators deserve to be deprecated
though.
What about:
These are provided only for compatibility with control file syntax:

evaluates as true.
I've updated my git accordingly in case you want to pull from it [1].
