looks good, but - it doesn't work. Caching and re-using seems to work but it
breaks different keymaps for different devices.

Just configure one keyboard to have a different layout in your fdi file (e.g.
de) and start a plain server and xterm. In current master, the keyboard has
the specified layout, with your patch it has the default layout (us).
Can you please test and fix this? Thanks.
