It's cool that USB PD means that a simple active connector and a standard USB power supply can replace all kinds of historical power supply adapters. However, it's kind of a drag that now there's a bunch of USB connectors that are invisibly incompatible - some USB power supplies support the Power Delivery protocol, some don't, and I don't know if it's safe to plug one of these "needs Power Delivery" devices into a power supply that does not support it.
How terrible an idea would it be to make an adapter that boosts the un-negotiated 5V that USB provides up to the 15V that (apparently) the IIc requires?
