Nah, I have a swap partition on an nvme drive, and I still get several minutes of unusability when I run out of RAM and low-to-out of swap, while the kernel takes its sweet time deciding what process to kill. It can get pretty frustrating, and sometimes I just don't feel like waiting and reboot. It doesn't happen often (possibly because I've learned to kill things like IntelliJ when I'm not actively using them), but when it does, it's super annoying.
