FWIW; I never questioned that and this was 100% clear to me, but it still
does not help if we have some use here, even if only legacy or restore wise
or what not, touch such things can easily break things in a subtle way, and
only get noticed in months or even years, we had such stuff a few times already,
so I'd be really cautious here - adding the "actual enforced limit" into the
description can also help.

I mean, I really do not think this crucial limit slipped and was left as is
for years...
