They already do e.g. renice is such a program.

No one's talking about LOWERING priority here. You can only DoS someone else if you can set negative nice values, and non-root can't do that.


This is DoS waiting to happen.

2. have a user space daemon poll running tasks periodically and renice them if they are running specified binaries



This is much too specific. Again, if the USER has control over this
list,


It would obviously be under root control.

And that means if someone wants to run a program which is not on the list but which requires (and deserves) higher priority, they cannot.
