Seems sensible. Only 2.6% of users (with telemetry enabled) are using 32-bit Windows while 6.4% are using 32-bit Firefox on 64-bit Windows[0]. 32-bit Linux might see more use however isn't included in the stats, only 5.3% of users are running Linux[1] and I doubt many enable telemetry.
Maybe they could also drop support for older x86_64 CPU's, releasing more optimised builds. Most Linux distributions are increasing their baseline to x84-64-v2 or higher, most Firefox users (>90%)[0] seem to meet at least x84-64-v2 requirements.
