[wp-hackers] Degrading gracefully with deactivated plugins?

[Robert Deaton]

If fixing templates that break when plugins are disabled is the goal,
then it would loop over all the plugins that are either active right
before the upgrade or maybe even all the plugins. This way, even
though plugins are disabled, its functions are still available, but no
hooks are added in in case the user didn't intend on that plugin being
active (like some of the defaults for example.)

The problem with the upgrading is that some users are suffering from
having their plugins active and some are suffering for having them
disabled. Maybe setting custom error handlers and code to reactivate
plugins if there is template breakage due to a lack of a certain
function, or deactivating because a certain plugin is causing foul
play. This could get quite elaborate but would be a very nice solution
to most of the problems.
