I'm not so happy about "...serves as a witness..." because that doesn't
make it less of an incompatible change.
However, since (as you know) I had plans to introduce such a filter node
myself anyway, I'll gladly let you take all the git-blame if something
breaks.
(And it should be easy for me to add the mirror target as another child
to the filter node.)
