i am at a link in file a that sends me to file b.  i click on it
[actually ret on it].  i pop the global mark ring.

you are saying i will always get back to the link in file a always?

now same example with the link pointing to file a.  will the global
mark ring take me there?  if not, then i will have to use local mark
ring.  this means i have to think about whether the file i was in was
the same file or not.  almost always, by the time i have done whatever
i was doing at target, that is totally forgotten.  the cognitive
overhead criterion in my first paragraph is violated.  so i /think/ my
statement about the back button behavior being broken with your change
is true.  please correct if that is wrong.

not asking you to.  my imperssion was that you could fix the bug by
having org mark ring push push to both rings.  you would keep the
current behavior of the org mark ring.  perhaps i misremember the bug.

i am saying that it's not a substitute for the current org behavior.

iiuc, of course.

i don't want to have to care about the global mark ring.  i don't use
it, but if i am forced to by your change, then and only then do i
think it's a problem that its behavior is too fancy.  i don't think
emacs devs will fix it.  it has a mysterious value to its users.
