This is not as powerful and solid as we want it to be. The trick is that we
can't rely on any metadata inside extensions to tell us they exist and
what functionnality they provide either. Python has the concept of trove
classifiers on packages but we can't extend them yet so they are of no use
to us.
In a future version, we will provide a mechanism from packages to support
a better detection.
