There is good an bad to anything. It is true we could have started releasing updates to one extension at a time with MySQLi support, but Dynamic Dropdowns would have likely been later on that list. The worst part would have been incompatibility if people had older versions and installation order would become relevant again. Also the cost passed on to our customers would have been more as they would have to upgrade the 13 individual extensions instead of having a lower combined upgrade price.
I appreciate your frustration and apologize we haven't been able to get out an update sooner. We will try our hardest to get it done as soon as possible.
