(Since my suboptimal udev solution I posted in #21 kept nagging at the back of my head, I put some more time into this. and will close 21 momentarily.)
If you use the below udev rule and choose a name that is lexically before /usr/lib/udev/rules.d/73-seat-late.rules, then it works with mode 0660.
I went for /etc/udev/rules.d/70-g13.rules and after a udevadm control --reload-rules (plus a udevadm trigger because I could not be asked to reach for the connector to re-plug), running ./Linux-G13-Driver as a normal user now works as expected.
