When I set the render engine to XPU the render takes quite a bit longer than CPU, and I don't think you can get the same effect as a shadow matte (Shadow Catcher) with an environment light hdri, unless this ability is hidden somewhere.

I think it would be essential for later compositing where you load the background footage.
It would be cool to have a ShadowCatcher Material.

I agree that it is essential that Karma needs a Shadow Catcher, Pixar has one with their USD render engine, so it is possible with Karma, I think all current render engines have a Shadow Catcher, you just need it integrated with the Beauty pass, not just in a Shadow pass.

In XPU it gets a lot slower using the bg plate node, and also the glossy reflections feature is not supported from what I've tested. A shadow catcher would be great indeed.

Ok, happy to see you guys see it also as an essential.
So I will send a feature request :-)

Is it now possible to implement a shadow catcher in 20.5?

I wonder if Copernicus can be used to generate a shadow matte?

Still looking for this solution all over the place.. no luck
