GPS isn't the issue. In fact there is also an RNAV (GPS) IAP to 12R
with the same FAF.

But, ATC couldn't issue the crossing restiction at ROYCE unless the
aircraft were on the approach at that time. A direct-to-the-FAF is not
allowed.

I most certainly can issue that restriction without the aircraft being
on the approach. It's merely a fix, if I want an aircrasft to cross
over a fix at or above a certain altitude I'll do it.
