I don't think we should even try and document what they should do:
they're evil and we should spend our efforts merging them into one instead.

Too much magic, IMO.  Let each case handle it manually, since I suspect
that every case will be different and the best thing to do will vary (it
depends on whether the two modes are still actively maintained, whether
by the same authors or not, the relative age and popularity of the
respective modes, ...).
