    How is this different from substitute-key-definition?  What am I
    missing?

You might be able to get the same jobs done with
substitute-key-definition, but this is a lot more elegant--the code
and the data structures would be simpler.  And this is more robust
in its handling of subsequent rebinding of the other keymap.

I think this is a great idea.
