I use a EF 40mm f/2.8 pancake lens on an RP with adapter and get very nice results. Could you explain to me why an R FF MILC pancake lens would not perform well?

I have the 40mm too. With an adapter it's not a pancake lens anymore. It's like 45mm long in total. An RF mount lens the size of the EF 40mm would either have a very short focal length (aka ultra wide angle) or need to be a retrofocal design. Neither of which work well without a ton of corrective elements.

We have seen MILC pancake glass for Sony E and Fuji X. The Sony 16/20mm lenses range from terrible to mediocre and they only cover an APS-C image circle. Fuji 18mm is better, but still not great. Samyang has a FF 24/2.8 which is small but no pancake, and it has a lot of problems. Sharp, but extreme vignetting. The way I see it, if it were possible to have made a decent short flange pancake lens we would have seen it by now.
