I'm not using swap partitions anymore at all. If a process wants to swap it is in my experience better off being murdered by oomkiller right away.

Funny. Your arguments are totally legit for a personal workstation. I recently added swap to a shared work server because without it, processes would get killed before we could notice and generally I'd like to be selectively kill processes.
I suggest the following compromise: Patch mm system to only swap processes that are currently stopped, and patch oomkiller to send SIGSTOP instead of SIGKILL. (And fallback to SIGKILL if the process doesn't stop.)

I mean the current system effectively does stop everything, but in a way that produces a lot of unnecessary IO. So just stopping the process that eats all the memory sounds like an improvement to me.
Thanks. Twitter will use this to make your timeline better. UndoUndo
