Btw, indeed Xi2 still doesn't pass > 248 keycodes, just tested that with
-git versions of X stack from about 2 months ago.
However this can be fixed relatively easily.
Maybe even I could do that.

The big problem is however about ability to map extended keycodes to
actions, thing that should be provided by XKB2, which we will see
probably when DNF is released on Phantom console...
Also this will need lots of changes in toolkits.
Thats the problem I don't have resources to fix.
