If somebody implemented it, yes.  I think it should be as easy as
calling signal_handlers_disconnect_by_func.

You need to break the mold.  Abandon what you already know.  Go with the

User data isn't really necessary, as Aristotle pointed out.  For
signal_connect_after, well, what about using »/=«?

The / kinda looks like a ramp which can be interpreted as a shoot.  And
as we all know, the big kids (aka. the default handlers) always skid
first.
