Well, you could in any case force the same decision to be made in every
invocation, for example by driving it off a GUC variable. The idea you
have here seems to be "it'll be the same choice in every sub-problem,
only we won't know which one afterwards", which doesn't seem at all
helpful for planner testing purposes.

I think dummy.c kinda proves my point: more than half the code is
accomplishing nothing except to duplicate the behavior of
make_rel_from_joinlist.
