Turns out locking your screen when you unplug a yubikey (should be similar with other devices) is harder than expected by looking at some examples found online. Maybe they have minimal use for the key and don't do multiple advanced things at the same time.
I can tell right out of hand that what's on #Fedora Magazine doesn't work properly: https://fedoramagazine.org/how-to-use-a-yubikey-with-fedora-linux/

These two forms work better because they are not run SEVERAL TIMES (which you can see with udevadm monitor --property --udev )
ACTION=="remove", ENV{SUBSYSTEM}=="hidraw", ENV{ID_FIDO_TOKEN}=="1", RUN+="..."
ACTION=="add", ENV{ID_FIDO_TOKEN}=="1", RUN+="..."

However I sometimes need to unplug and plug the device again in order to force a mode transition and I don't want an immediate lock. So it turns out now I get other complications:
1) udev RUN action need to be *quick* it can't even wait 5 seconds
2) so my script forked to another one in background that will do the timeout loop
3) except even that script is killed before the loop ends so the screen is not locked

I tried changing the script calls to systemd oneshot services, but it appears that somehow udev is still tracking all the forks and killing the process mid-loop.
So now I'm at a loss.
Any ideas?
