We need to have a change in behavior that allows 'M-x package-install' 
to upgrade built-in packages. But that shouldn't automatically mean that 
package-menu-mark-upgrades marks all built-in packages for upgrade, or 
package-upgrade-all (nee package-update-all) does that either.

We could have another option that enables the latter to upgrade all 
built-ins too, of course.

Regarding the currently proposed user option, does it make sense to you 
to have such option that decides whether package-install upgrades 
built-ins? Whereas one can always upgrade a built-in package using 'i' 
(package-menu-mark-install) in the list-packages menu, no matter the 
value of that option. I get the backward-compatibility intent, but user 
options should also do something logical from a user's point of view.
