So seems like SDL covers everything Winit does plus much more (including at least some stuff WGPU does), and you really don't need to have all supported hardware to work on bugs in it - which would be a nightmare, since aside from the platforms you mentioned it supports stuff like Haiku, PSP, OS/2, Nokia N-Gage or QNX, and even console SDKs behind NDAs that aren't available publicly. Its video drivers and render backends are all separated from each other. In all my adventures with fixing bugs or implementing new features in its Wayland backend (such as HiDPI support) I never had to touch the platform-independent stuff. Not saying that it doesn't happen in general, but I personally never had to do that. It smells like nothing more than a maturity issue. SDL is almost 25 years old at this point.
