I think it is worth *some* effort, at least as far back as we want to
claim that we maintain pg_dump and/or psql compatibility, assuming it is
not too onerous. For instance, I wouldn't want to clutter buildfarm or
CI dashboards with testing these branches, unless it is well isolated
from regular ones; we shouldn't commit anything that's too invasive; and
we shouldn't make any claims about supportability of these abandoned
branches.
As an example, I did backpatch one such fix to 8.3 (just over a year)
and 8.2 (four years) after they had closed -- see d13f41d21538 and
105f3ef492ab.
