Comment(by scribu):

 For network plugins, you can use add_site_option() etc. to store a
 separate array of version and then you would have to run the upgrade
 procedure for each site. Similar to #14170

 A more pressing problem is that in your current patch, you tie the version
 update to the activation procedure, so we're back where we started.
 Upgrades shouldn't be tied to activation at all.

 The way I see it, the active version should be added and updated from
 register_update_hook().
