I think 2 is the right option.  package.el was designed such that you
can have various versions of a given package installed.  Only one of the
can be activated at any given time, because Emacs Lisp doesn't provide any
way to do better, but having both Org-9.1.9 and Org-9.2.6 installed
should be a perfectly normal situation.

Any misbehavior that results from this should be reported as a bug
(especially if it can be reproduced).
