User d9k on IRC found the culprit. It is low-memory-monitor. The latest commit [1] for it tries to not mess with the value with 1 is set, but it should not mess with it ever.

The same documentation on that commit references [2] where it says:

Note that the value of ``/proc/sys/kernel/sysrq`` influences only the invocation via a keyboard. Invocation of any operation via ``/proc/sysrq-trigger`` is
always allowed (by a user with admin privileges).


[1] https://gitlab.freedesktop.org/hadess/low-memory-monitor/-/commit/11560bc102941c95890c0852f2d9b166853b4f6a [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/admin-guide/sysrq.rst

Will submit a bug (if d9k already hasn't done that).


Reported upstream and a tracking bug on bugzilla
