That's all good for me, but as usual I would like to have some tests. It doesn't seem it should be hard to add support for comparison samplers to the shader runner, or I am missing something?

Comparison samplers by themselves aren't hard, but it does mean we need to add stuff for depth write and also support rebinding a DSV as an SRV. (Or blitting?) Both things that'd be nice to have eventually; I'd like everything to have at least some manner of test even if it's not in the shader runner...

Mmmh, maybe I am misunderstanding what `SampleCmp()` does. Based on what I can read in https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/dx-graphics-hls... it doesn't look like that you have to deal with DSVs:
For each texel fetched (based on the sampler configuration of the filter mode), SampleCmp performs a comparison of the z value (3rd component of input) from the shader against the texel value (1 if the comparison passes; otherwise 0). SampleCmp then blends these 0 and 1 results for each texel together as in normal texture filtering (not an average) and returns the resulting [0..1] value to the shader.
It seems that you just have to create a texture with some data in the third component and then sample it. Am I missing something?
If I am indeed misunderstanding and it turns out that having a non trivial test would take a lot of work, then ignore my comment.

Um... that's a good question. Comparison sampling is traditionally used with depth textures, I have no idea if it works with color textures. If we can write tests and they work, then sure, but it may very well be the case that it doesn't work, or at least doesn't work consistently.
