Its not going to happen in the future either, There is never going to be a desktop motherboard that delivers full spec (100W) USB3 power delivery to say, 6 ports at once, or a laptop even capable of delivering to 1. The USB spec is too ambitious and its inevitable that some use cases are mutually incompatible.
