1) in the Microsoft days I would have a lot of available ram, bur windows still would aggressively swap, and I would get enraged when changing to an app that would have to swap in while I had 4gb of memory free

2) the os tried to be magical, but a swap thrash is still crap... I would much rather oom kill apps than swap thrash. For a desktop user: kill the fucking browser or electron apps, don't freeze the system/ui.
