I think you should be able to do this by simply adding some entries to 
hwdb.d/60-keyboard.hwdb - if you set the scancodes to !, udev should 
then tell the kernel to synthesise keyup events.

NACK. There is "no new force-release quirks" policy in linux kernel.

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8b8a518ef16be2de27207991e32fc32b0475c767

"force release" quirks are handled by userspace e.g. by udev rule. There 
is hwdb database where can be put DMI of problematic/broken machines 
together with keys which should be force-released.
