I would understand your concern here, except the original Qi standard existed and it never stopped anyone from developing faster or better wireless chargers. Chargers that when paired with their own devices, offer faster charging and other functionality.
Both generations of Pixel Stand offered standard Qi charging rates when not paired with a Pixel device.
They didn't perform worse than a standard charger would with other devices.
There's no reason the same thing can't happen again, and there's also no reason that all of the members of the Wireless Charging Consortium can't contribute work to develop the standard further, the same way that Apple has done.
