I also attempted some "simple" hacks in both libXaw and libXt
to see if I could workaround the problem there, but no luck. I
suspect it will cause problems anywhere Meta is used for
shortcuts tough.

  In my case, it removes functionality from xedit and emacs;
in emacs still can use Esc instead of Alt/Meta.

  Most commonly used xedit actions are Alt+. for "tags" and
Alt+d for "delete word".

commit 4fa3872dc2bcfd6d1fc88d0a94c7071683eea899

    Input: Remove core keysyms from KeyClassRec
    
    Instead of always keeping two copies of the keymap, only generate the
    core keymap from the XKB keymap when we really need to, and use the XKB
    keymap as the canonical keymap.
