You simply don't listen.

Because if they are supposed to be different when bidi is switched on,
that makes them different.  You don't gain anything by replacing
left-char with maybe-wrongly-backward-char-if-user-is-Drew.  You still
need something different from backward-char.

Differing behavior is done by different keybindings.  That's where we
are.  If you worry about remapping of backward/forward-char, one could
make left-char/right-char look up the respective remap.  So far I have
seen no indication that there is any actual problem (instead of
hypothetical problems) solved by this.  So this complication does not
seem worth the trouble.  Worse, it will cause people not to fix stuff
that will break under bidi.

The answer is no.  Not reasonably.  I have little doubt that you will
not accept this answer and prolong this thread as long as anybody cares
to react and then some.
