I considered that, but I don't think it's worth it.
This is analogous to how TeX's standard \left- and \righthyphenmin work:
they're just integer parameters, you can set them as large as you like
with no complaint from TeX (well, I suppose there's a 32-bit integer
limit or something...), and reading them back will give you the value
you specified, but internally they're clamped to the range 0..63 when
they're used, and setting them larger won't make any difference.
This kind of behavior is typical of TeX's integer parameters. Setting
\tolerance=9999999 is valid and generates no warning, even though it
won't behave any differently from \tolerance=10000 as far as TeX is
concerned.
