I kind of don't see the benefit, as it's still going to use only the window, input and platform integrations features, while SDL3 has a whole software renderer built-in and much more.
You can compile in only the used stuff with various build flags, not sure if they did that though. I've done that before to make a pared down SDL that only does audio playback.

Does this mean SDL3 has a built in 3d renderer or it's the modern meaning where anything is a serverless renderer or something like that?
This fixed a lot of bugs related to input. If you scroll down to the bottom of the page you can see all the bug fixes from this snapshot, there are a lot related to input.
