There are other hypotheses that predict the same result.  <shrug>

Besides, it is not conclusive that GPS utilizes GR to do so.  To do
that, it requires a ground-to-satellite synchronization.  This is just
too costly and too error-prone.  In addition to the error associated
with downlink from satellite to the ground, there is just too much
error compared to satellite-to-satellite synchronization.

With physicists as consultants, GPS most likely did start out with
ground-to-satellite synchronization, but engineers quickly figured out
the unnecessary introduction of error can be eliminated if satellite-
to-satellite synchronization is implemented.
