Currently the Maya `pluginInfo` command can only list all loaded plugins and plugin paths.
Please add functionality to also be able to query all available plugins as they are listed in the Plug-in Manager easily in a single command query.
Currently this listing for Plug-in manager lives in `.mel` files with local `proc definitions so the functions are not accesible outside of it (plus they are not written in a way that would really allow accessing them.)
I threw together this https://gist.github.com/BigRoy/4ecb17a44650764228970f0e05630186 to mimic what the Maya MEL scripts do - still it'd be great to get a native command we could call to get this same info from Maya, e.g. `pluginInfo -query -listAllPluginsPath`
Similarly, the hardcoded "available plug-in extensions" that are supported by Maya would also be nice to be accessible, e.g. `pluginInfo -query -supportedExtensions`
