Would it be possible to keep the previous message and just append in const contexts. The trait bound message appears again below anyway, so that would seem easier to read by humans

The way to approach this might be adding a flag to the rustc_on_unimplemented directive that allows appending in const contexts instead of falling back to the generic message.

Hmm.. I was hoping we could patch rustc_on_unimplemented to just append this, but I forgot that the messages are entirely custom and could make the wording weird or nonsensical.

So... a required field for rustc_on_unimplemented with an append snippet or just an entirely new message?
