At the moment all plugins in the store have to go through me.
The cloud builds can be easily replicated for local testing using the mod-plugin-builder.
So if you get it working with that, it will speed up the process of getting them into the cloud/store.
This is temporary of course.
We hope to have a developer online service for handling this soon.
That has to go through me too.
In the end it's just a on/off flag, but of course we need to ensure the plugin is really stable.
Also if there are already too many similar plugins we might not bother too much as the current selection is good enough already.
In the end, if enough users request it, we'll move specific plugins to stable.
(with some internal testing of our own too)
