Remember that on the ILS, GS intercept at published altitude is the
FAF, nothing else. Don't wate time here flipping back and forth.

But then you can't verify your altimeter's accuracy when crossing the
FAF.

Only if the GPS goes TU - otherwise the GPS will give you at least as
good a fix as a cross-radial.

Oh ok. Initially you said "GS intercept at published altitude... nothing
else" identifies the FAF. (Although I'd still be reluctant to rely on a VFR
GPS for identifying a fix.)
