What exactly is non-standard about it?

Once you hit the soft cap of 3 amps, you're supposed to increase the voltage. The 3-5 amp range is only supposed to be used at 20 volts.

That's all good if your sink supports sinking 20V, but some don't. Anyway, those tables describe minimum required currents for a given PDP:

Sources can support more and it's not against the spec, as long as you detect the 5A cable.

It's not like you go directly to 20, you go one step at a time.

They can but how many do? If you want to play nice you shouldn't require that for your device.
