Hi pyrocrig,
It is actually better that the server behaviors were removed from CC (which is faster than CS6 actually), as the code generated using them is already Deprecated... In a near future (when your hosting provider updates the PHP version) the pages created using this deprecated code will just stop working. The original MySQL extension has been deprecated since PHP 5.5, and will generate E_DEPRECATED errors when connecting to a database.
Anyway - you can install the deprecated server behaviors in CC if you wish
