I don't claim to have an opinion about how convenient it would be
for users to not need an init shim. I do claim to have a qualified
opinion about how hard it would be for us to support the case. It'd
hobble our ability to detect child-process bookkeeping errors, and
it'd put constraints on how we manage the postmaster's signal handling.
Maybe those constraints will never matter, but that's a contract I
don't really want to buy into for this seemingly-not-large benefit.
