In the #12915 thread both Juri and I argued for having
(multiple) means of _user_ control.  And several such means
were suggested.

I said, for example:

  Give users the _possibility_ of including, as part of
  `file-name-history', file names not actually typed in the
  minibuffer.  But give them also the ability to _choose_
  which such names get added, as defined by how the files
  were chosen for access.

Juri said, specifically to argue against your #1::

  Since this is a matter of personal preference, I think
  not Lisp callers but Emacs users should be able to specify
  what to add to the history.

There are lots of good suggestions in the thread - many
specific and some based on actual implementation and use.
Asking "Anybody got an opinion?" is an invitation to
ignore lots of opinions already carefully expressed.
