--------------------------+----------------------------
 There are several bugs/inconsistencies when WordPress handles plugins with
 unmet requirements.

 - A plugin with unmet requirements cannot be installed or updated when
 using the UI, but this is possible to do/there are no checks when a plugin
 is installed or updated directly (with FTP, SSH, or git/svn).

 - A plugin with unmet requirements cannot be activated if already
 installed (happens only when a plugins is installed/updated from FTP, SSH,
 or git/svn). But if the plugin is already activated, it is not deactivated
 and continues to load.

 - The UX can be better. The warnings in wp-admin when a plugin has unmet
 requirements are somewhat inconsistent, and there are no email
 notifications if any of these errors occur automatically (for example a
 script is running on the server that uses svn or git to update plugins).
