Should this be moved to the Steam client tracker? If it works for native games, there's no reason it can't work for Proton games as well.
Hello @aeikum, this scenario has come up before on the Steam client side at https://github.com/ValveSoftware/steam-for-linux/issues/6306 and the previous assessment should still be true. If there isn't interest in handling the direct request, then this is better handled by a short launcher script similar to the one proposed in that issue report.
I don't think we want to add this. Please use a wrapper script like suggested.
