yes, there's definitely a bandwidth overhead with xml compared to json. that was an important factor in the shift i suppose. but then we have things like graphql, which has pretty much erased all those gains. you can also do tricky things like using binary on the wire and transforming at the endpoints.

it would be nice to see if fundamental xml tech can be improved in a new hardware and software environment. afaik, there hasn't been much if any innovation in that space in recent times. would love to know if there has.
