breaks commonly used plugin technique for network activation
|Reported by:||iandunn||Owned by:||nacin|
 removed $_GET[ 'networkwide' ] during activation/de-activation, which is commonly used by plugins to hook into the process as described in a popular post by Shiba. This was discovered and documented by WPGetReady.
Instead of being immediately removed without warning, I think it should have followed the standard deprecation process so that developers can have time to update their plugins. $_GET[ 'networkwide' ] should be re-introduced in 3.4.1 in a deprecated fashion, and then completely removed in the future.
