Couldn't we scale the rounding, e.g. allow small allocations as we do now,

That'd make the translation considerably more expensive. Which is important,
given how common an operation this is.
Perhaps it is not practical, doesn't help, or maybe I misunderstand, but
my intent was that the rounding be done/enforced when setting the GUC
value which surely cannot be that often.
