Xilem seems to be heavily focused on using WebGPU. One doubt I have is: is it possible to have tight integration with the system's compositor using such an abstraction? For example, on Windows looking at the documentation for the DirectComposition, it seems that things are designed precisely to work optimally with DirectX. So my impression is that one would really need to use the native graphics APIs on each system to achieve optimal input latency.

It's a good question and one we're looking into. We're not planning tight integration with the system compositor on our 2024 roadmap, partly because it's extremely platform dependent, and presents compatibility challenges (you basically don't get it on X). But even for damage regions, which is on the roadmap, we're going to need to extend wgpu.
