I opened an issue on the repo, about adding a small blurb about the public plugin repo guidelines.
Specifically, your meta-plugin conflict with #8 and #13:
8 The plugin may not send executable code via third-party systems.
Externally loading code from documented services is permitted, however all communication must be made as securely as possible. Executing outside code within a plugin when not acting as a service is not allowed, for example:
- Serving updates or otherwise installing plugins, themes, or add-ons from servers other than WordPress.org’s
- Installing premium versions of the same plugin
- Using iframes to connect admin pages; APIs should be used to minimize security risks
13 The plugin should make use of WordPress’ default libraries.
WordPress includes a number of useful libraries, such as jQuery, Atom Lib, SimplePie, PHPMailer, PHPass, and more. For security and stability reasons, plugins may not include those libraries in their own code, but instead must use the versions of those libraries packaged with WordPress.
You'll want folks to have a heads up, so they can choose to use your plugin, or be listed.
