We can't do that. We're not the makers of the plugins so we have nothing to do with it besides the few that were created by our own admins.
And I would say that using a pre-release is not a good idea. It is not a finished product at all, so therefore it is not a good thing to base something off of.
I would compare it to eating a meal that has not been fully cooked. There may be bacteria in it, there is flavors that would have changed throughout the full process of cooking, and many other things. Instead the fully "cooked" meal should be eaten and enjoyed, because then it is finished and is "clean".
As I've noticed there are things in pre-release that are not added into the final update that they make. It's simply a test and a bug-run as well as a fun way to play through some features that could potentially be added.
