Hm, yes -- if we do this, we'll end up with all users both having that
variable saved in their init file in addition to the multisession
storage.  Hm.  That sounds really confusing.

I can also see people running into difficulties when switching between
older and newer versions of Emacs, and Emacs becoming very confused.

Hm...  I don't immediately see any way to make this work seamlessly in a
way that's backwards/forwards compatible.
