uinput module not loaded automatically anymore

I use dwm on Arch and in my autostart.sh I start KMonad. This requires me to be member in the uinput group (what I am). Since a few days starting KMonad fails with:

    
kmonad: /dev/uinput: openFd: permission denied (Permission denied)

  

(Same when I try to start it manually.)

The workaround is to run sudo modprobe uinput and then to start kmonad (again).

I just don't understand why this is necessary now. I have this udev rule defined:

/etc/udev/rules.d/90-kmonad.rules:

    
KERNEL=="uinput", MODE="0660", GROUP="uinput", OPTIONS+="static_node=uinput"

  

I guess this broke because of a sudo pacman -Syu. Has anything changed in the last few days? I can't find anything that looks related on Arch Linux.
