That’s pretty much the “we should all put PoE everywhere” debate, and I don’t think that’ll happen (or is a good idea) - and that’s coming from me as someone with switches providing 1.5kW of PoE power budget in the garage.
The alternative would be a shared conductor like we have now - and while that is working will in data centres doing a conductor in the required dimensions for that would be too big, and potentially dangerous, so that’ll happen even less.
