This is not like 20 years ago when every manufacturer had a different size barrel jack connector and a different polarity and a different voltage, that is when we needed this law, the situation has now resolved itself and they decide to introduce a stupid law to say look how good we are - 20 years later.

OK, let's try this again:

It's not about the phones.
It's not just about the phones.
This is more than just the phones.
More devices are covered byt the law than just the phones.
Not just the phones are covered by this.
More devices have to use USB than just the phones.
The phones are not just the devices this law covers.

Where phones go the rest follow :)

I haven't checked whether the current versions support this, but the original version of USB-PD was negotiated over Vbus, and therefore worked with standard USB-A plugs.

There was something with comms on the power lines, but it used a slightly different A and B plug variant? Never seen it in the wild so unsure if it was ever used, or has been dropped.

You are pretty much correct. Some electronics parts are only available is VERY tiny micro BGA packages because mobile phones use them. You cannot get them in larger SMD packages. Quite annoying. No technical reason why, other than phones is where the $$$ and volume are.

Yeah, unfortunately I can't quickly locate a copy of the spec for that. I do see something about 'mechanical marking', so perhaps this meant a notch and a switch inside the port, or something along those lines? Certainly current PD standards use the side channel, and solutions like Qualcomm Quick Charge use the data pins - or at least did, and are now just an alternate protocol coexisting with USB PD. Soon to be dead and gone to kill a chunk of their proprietary charger game.
