> It is unusual. I'd even go as far as to say that it is an awful and stupid decision to do this at a time when USB-PD operating at higher voltages is finally becoming somewhat commonplace (common, as in: we might have extra junk laying around that can do it) Not even "junk drawer gear". USB-PD is recent enough that any gear supporting a good cross-section of that spec will be recent if not brand new. As 1 data point: I recently bought a USB-C power adapter that supports USB-PD up to 35W at a variety of voltages & negotiation methods. A RPi5's power needs are well within that 35W. And yet, beside supplying 5V @3A (which comes with its own set of issues / limitations), it'll be largely useless as a RPi5 power supply. Regardless of cable used. Many USB-PD power bricks will be in same boat. So indeed this is a stupid design decision on RPi's behalf. I've read & understand their rationale for that decision. But it doesn't make it less stupid. Other SBCs use USB-PD as intended (in this case, @ higher voltages like 9, 12 or 15V, or even variable) no problem, and without needing special 5A rated cables. The onboard electronics / ICs to do this are cheap & plentiful. Okay - RPi's rationale is an excuse. Not a good one. Supplying a 5V/5A brick themselves, doesn't do much to paper over that fact.
