 I considered this overnight and decided to do it as part of the global
 database upgrade routine. There's a very slim chance this has happened on
 sites and having the `false` in there isn't a big problem so I figured
 it's okay not to do it as part of a cron array upgrade.

 I've [https://github.com/WordPress/wordpress-develop/pull/1605 linked a
 pull request] to this ticket to go in with @jrf's.
