Well, the previously agreed-to syntax was SET STATISTICS DISTINCT.
I don't see a problem with using "distinct" and "inherited_distinct"
or something like that. "ndistinct" is probably not a good name to
expose to non-programmers.
The must-RTFM argument is fairly weak, though, since these are knobs
that only advanced users would twiddle anyway.
