So you get the keybinding "backward-char" for C-b, and the keybinding
for left.

Namely two different bindings, one looking up backward-is-always-left,
one ignoring it.

What is that supposed to buy you over backward-char and left-char?

So it appears that you want to have left-char and right-char, after
picking their choice of forward-char and backward-char, to check if any
of the latter have a remapping in place.

That question has been answered.  That you refuse to hear the answer
does not change that.
