The problem is, once we implement such a mode, the word "reverse"
becomes ambiguous: it no longer unambiguously says that we go
backwards.

That prospect was the original reason I mentioned the possibility of
introducing such a mode in the future.  And that was the reason I
still think it's better, at least in principle, to say "backwards" or
"back", because that's unambiguous.
