I think so too.

I had to deal with the same problem in table.el and noticed Kim's
original example of substituting self-insert-command with
x-self-insert-command had more meaning than he mentioned.  When using
substitute-key-definition with global-map as the OLDMAP, it is not
easy to substitute all self-insert-command since some global-map
entries are mapped to a symbol whose function definition is a keymap
or even a "would be loaded" keymap (i.e. iso-transl-ctl-x-8-map).  In
this case, the original keymap can not be altered so a copy of the
original must be created and then map it to an alternative symbol and
be placed in the KEYMAP.  This symbol hunting must be performed
recursively.  The proposed method eliminates this cumbersome work all
together.
