As a minor nitpick, the "The query always succeeds and returns EGL_TRUE, and is set appropriately" line probably isn't necessary, since that's the default assumption for EGL functions. Other than...

I'd say it's obvious enough what each attribute is.

For adding a new device, we don't need EGL to notify the application. An application can carry on using whatever device it was using and still work just fine. If...

What `EGL_NATIVE_VISUAL_ID` is depends entirely on the platform. With EGL_KHR_platform_gbm, it's a fourcc code, but with EGL_KHR_platform_x11, it's the XID for an X Visual. EGL_KHR_platform_wayland and EGL_EXT_platform_device leave it undefined,...

Is a fourcc code meaningful for any consumer type other than EGLImages?
