I'm not actively opposed to a randomize hint, just if there's something
more generically useful and meaningful that'd also work, it would be
better, i.e. it would be better to annotate WHY you wouldn't want to
randomize it, is possible.

I think this is better. The default for controls is to be able to set
to anything. Some well-designed are specifically designed so that
basically any setting will do something reasonable (much like what Moog
strives for in hardware).
Ports that, for some strange reason, shouldn't be set to a valid value
in their range, are definitely the exception, not the rule.
