P-channel devices

It's a while since I did my semiconductor physics - we touched on III-V devices for about half a lecture (GaAs LEDs and HF transistors), and SiC was nothing other than carborundum then.
There are PNP bipolar transistors in both silicon and germanium, P-channel MOSFETs and even P-channel IGBTs*, but I have never seen any P-channel SiC or GaN devices.
Is this due to a lack of demand, or difficultly in making them (like P-channel valves, for instance, or something like poor carrier mobility)?
