Sorry; I thought you meant dumb extensions wouldn't work with PD, didn't have the wires or whatever.Ooh can you show my where in the Type C specification this is allowed ?Some dumb extension cables are but whether they can carry 5A of current is another matter.USB Type C extension cables aren't compliant with the PD specification.
No, USB-C extension leads aren't a part of the USB-IF official spec - but, so what ? Manufacturers will still make and sell them. The official spec has elicited shrugs for decades, ever since USB devices used USB-A sockets and needed USB-A to USB-A cables.
It's not so much they shouldn't exist according to the official spec but whether they work, and why not when they don't. Not being a part of the official spec is not going to be the reason they won't work.
