I think the difficulty is every frame runs in a separate process

So and oom killer would have to be smart enough to group each tab’s processes for tabs with iframes. Additionally I think gpu, media decoder, and a number of other processes also run independently, so it would have not kill those (or if it did, all the tabs would probably die, functionally not too far off from killing Firefox)
