intersection, LOM, or DME, that's an acceptable substitute for a locator
beacon.
The FAF on an ILS is glideslope intersect, not the LOM, DME etc which are
not required.

Ahhh, but suppose your glideslope fails (onboard or on the ground)
after this "not required" intersection (with the "X" on Jepp charts)?
Suddenly you are doing a localizer approach and the FAF identification
becomes much more useful as a place from which you start your timing.
