As a workaround, a timer job/script writing every few seconds might do the trick.
I tried a systemd timer but it floods my dmesg every time it triggers and also caused weird lag in systemd monitoring, perhaps writing to sysfs constantly has a noticeable cost. Maybe someone could hack a kernel option to force it to high as a temporary workaround? Unfortunately I'm ignorant in C.
