Some of those tradeoffs are made by the distributions - the kernel has (always) offered various schedulers but you have to pick one.

Umm, mainline kernel has had only CFS scheduler available for the past 15 years. Sure, there are some out of tree options available, but with those comes the common problems of using out of tree patchsets.

Huh, maybe my kernels have always had patchsets, because I always get an option to change the scheduler (but never do).

Actually the history of how pluggable schedulers came to be in the kernel is a fascinating one, and one I recall watching unfold in the mid-2000s. There were out of tree schedulers and a pluggable scheduler implementation put forward by Con Kolivas before Ingo introduced the CFS patch, and a lot of frustration that pluggable scheduler patch sets were rejected up until that point.
