For such scheduling decisions to be globally good, for example, to figure out that such and such thread should make progress to unblock something, to unblock something, to react to the user input, to draw something on the screen, the kernel needs a lot of smart behavior. 
 We have observed regressions in UI responsiveness on Linux and Windows when clangd is doing background indexing at normal priority.

I'd love for the kernel to figure it out automatically for us, but the experience tells us that we're not there yet.
