That's great news, thanks!

I think tlp that James mentioned is pretty much the only project that
has stuck around. There have been some other efforts sprouting every
now and then, but I guess they got abandoned when their creators moved
to different machines and lost interest.

I've been using these two scripts on various systems:
https://github.com/philipl/evdevremapkeys
https://github.com/pronobis/evdevremapkeys

One is a fork of the other, with their main difference being that the
fork implements N:N mappings. They both work under Xorg and Wayland,
because everything happens at a lower level, it's like plugging in a
new input device. Your engineers might be interested in that.
