I've had a series of Canon powershot cameras that have all used more-or-less the same Li-ion cell design[1] and I've been able to swap batteries with them. They're big enough that third parties have even offered replacement batteries.

There is probably room for standardization of a compact, rectangular, rechargeable battery of roughly those dimensions. Is someone pushing for it?

I don't think anyone is pushing for that, though sometimes a company will design a device around another company's battery design. There's quite a bit of small photo/video lighting that uses Sony NP series camera batteries. Those are just a pair of 18650s in series inside a plastic box.

It seems to me the size of the G7X could have been designed around a 14500 cell instead.
