I can easily imagine current-active-maps playing a role in the
implementation of a solution to the bug I linked, but I hope we agree
that it is not a solution in itself.  From what I've seen, the confusion
and frustration of less experienced Emacsers in this area is most often
related to key binding precedence/shadowing, and this motivated my
suggested change to `describe-key' output[0].
