This assertion is incorrect.  The real goal of right-word is to
provide a command that works as users expect in both left-to-right and
right-to-left contexts.  The alternative would be to request that the
user should decide whether to use M-f or M-b to go in a particular
direction, and that's a non-starter.

This command has two bindings not because of its importance, but
because other programs out there use those bindings.  Emacs is
following the expectations of the users here.
