If that's the approach you want, it's been possible for decades:
"set join_collapse_limit = 1" and away you go. I don't feel a
need to invent a different version of that for star schemas.
I do not think this patch should have ambitions beyond the stated
one of avoiding useless join-order search effort. If you try to
load more than that onto the plate you'll probably end in failure.
