Hmm.  I'd say we should only remove it when there is significant cost
associated with it.  Since we already have it, we might as well keep
it.  Maybe it will make someone happy. :-)

It would good enough to just document the default case and only
mention somewhere that the backtrace can also be displayed backwards
but that the documentation assumes that it is not being done.

Is that so?  The 'backwards' option should only matter during display
and we already have that code, right?

On the other hand, if you need to write new display code for the
debugger and the backwards option makes that significantly harder, I'd
say it is OK to remove it.
