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.

But, in essence you are clearing me direct-to-the-FAF. This is not an
en route fix or even an IAF or earlier. Only in limited circumstances
are you allowed to clear me direct to an RNAV IF. I certainly don't see
how you can make me cross a FAF unless you have correctly placed me on
the IAP.
