As far as I can see, step-down fixes on GPS approaches are always defined by
a distance to the threshold. Are there exceptions?

Do GPS approaches exist with waypoints (forming part of the approach
sequence) between the FAF and the runway threshold waypoint? Or is it
guaranteed that after passing the FAF, my distance-to-waypoint will always
be the distance to the threshold?

Counter-examples useful. References to publications guaranteeing no
counter-examples even better!

Thanks

Did you mean strictly "distance to the threshold"?
Where the Missed Approach Point is short of the threshold,
stepdown fixes are likely to be defined by distance to the MAP.
In Colorado, here are a few examples which illustrate that:
KCAG (Craig) GPS Rwy 7
KDRO (Durango) GPS Rwy 2
KEGE (Eagle County) GPS-D
KHDN (Hayden) RNAV (GPS) Y Rwy 10
KLXV (Leadville) GPS Rwy 16
KMTJ (Montrose) GPS Rwy 17, GPS Rwy 35
KRIL (Rifle) GPS Rwy 8, GPS Rwy 26
Most of those stepdown points are defined only by distance,
but at least in the case of Hayden, ZULON is a named stepdown fix,
at 1.9 nm to RAPVE, which is the MAP located 1 nm from the runway.
