Curious. On our production machines we seldom have less than four
PostgreSQL instances on any given machine.
Perhaps we're wrong and should stop that, but I'd need have to have
evidence WAY more specific than some devoid-of-details claim of "It is
potentially problematic."

What is happening is entirely proper.
PostgreSQL provides mechanisms; it does NOT impose policies. This is
not a mistake; it is intentional.
If you require a policy, then YOU are free to choose the policy that
YOU need. You're not forced to accept other peoples' policies that
may conflict with things in your environment.
