Hm ... hstore_plpython and ltree_plpython still pass regression check in
9.6, so it works for at least moderate-size values of "work", at least on
Monterey. But in any case, if there's a problem there I can't see us
doing anything about that in dead branches. The "keep it building" rule
doesn't extend to perl or python dependencies IMO.
