USB-C Charging on the PBP?

You are correct - the original context of mine and everyone else's "doesn't support PD" was as in "doesn't take full advantage of PD when it comes to charging". And then I misread the reference to the power-specific section of the wiki as a reference to the USB type C port in general, which IS of course PD as without PD DisplayPort alternate mode would be impossible, and that lapse of attention got me all TRIGGERED *facepalm*. That said, despite unintentionally offending MtnSk8, I think indeed something good came out of it - I believe I've gained a bit more understanding of how exactly USB negotiates power and I hope I was able to clarify at least some key aspects of it to others as well.

But back to the power-specific wiki section - from what I understand, it is still correct to talk about the USB-C port being PD even in that context, since it's more about the mechanism of negotiating the current/voltage rather than about the amount of said current and voltage. On the question of "quickcharge" - I do think that is a misnomer, primarily because there is Qualcomm Quick Charge which is a separate and until v4 incompatible with PD protocol. But in defense of whoever put it there - QCv1.0 could allow just 10W, which is only 2/3 of what PBP can take, and while 15W isn't all that quick at the battery capacity we have in PBP in the phone world (most of the consumer mobile uses for ARM SoCs, where all this terminology got established) that would be pretty quick.
