I really can't understand who it could be effective.  My reading of the
code tells me that function binding is never used.

That's what I would expect, since I think this fset is a no-op.

That's because that's what you told it:

  :keymap <exp>

says to use the value of <exp> as the keymap, so ":keymap
allout-mode-map" says to use the value of the variable as the keymap.
If you want to use a symbol, then you need to quote it.

This said, you can modify a keymap after the fact: as long as you don't
do a (setq allout-mode-map <newmap>), you can modify allout-mode-map on
the fly and those changes will take effect immediately without having to
use an indirection through the allout-mode-map symbol.
