If you have a system with long-running leaky browser instances, Alt-SysRq-F is a lifesaver. It calls oom_kill, sacrificing one process to save the rest.
I do, and used it today as well. My AMD gpu sometimes when booting fails to set the correct resolution on the 3rd display, and that causes the graphical session to freeze for some reason and I have to force a restart with sysreq and start the graphical session with a weird script that sets a custom res lol.
Side note: does anyone enable or use the magic sysreq key anymore?

Honestly no. Haven’t found the need.

It may actually be a security hazard since there is a small chance of e.g. OOM killing your lock screen or other such process.
Not on Wayland
Please tell me that needs physical access to work. Now that I think about it - how does sysrq even work with laptop keyboards?
I use it for fun
And sometimes for testing system survivability
Gotta keep that kernel on its toes.
