I personally would love to see sched_ext to land upstream for the simple reason that nobody upstream cares about desktop Linux and regular user needs for scheduling.

Having a way to build optimized schedulers outside of the kernel to bypass CFS and EEVDF and their flawed behaviors for regular users gives us an actual chance to deal with long-running responsiveness and performance-under-load issues that desktop Linux users observe that otherwise drive them to use alternative kernels that patch in other schedulers (like Con Kolivas' MuQSS and its predecessors).

Improving the desktop experience was definitely one of the biggest targets we had in mind for potential improvements that could result from sched_ext. See this for an example of efforts to improve interactivity: https://drive.google.com/file/d/1fyHt9BYGha6apl7HAkibwpy5.... The techniques used there could also be added to EEVDF, which I'd be super happy to see.
