a) Can't parse your last paragraph;

b) I vaguely remember indeed somebody wanting to propagate the code
   from imenu-go back into etags; it may be that pop-tag-mark has the
   functionality of imenu-go (at least when imenu-go works with tags;
   it can get info where-to-jump from other sources too).

c) My experience with my code propagated back to Emacs is very
   negative: a lot of times the resulting code has only subset of
   the original functionality.  So I have no incentive to check how
   well pop-tag-mark behaves...

Hope this helps,
