Document reference implementations and supported features

[NSeydoux]

In a thread on the Solid forum, two users make a good point that it would be convenient to have a place documenting the features of the specification supported by existing implementations. I guess this is should eventually be automated using the test suite, so would it be worth to have a table of features and their support ?

Right, the test reports reveal that data. Upcoming meeting agenda will dive into test suite: https://hackmd.io/TqfZNJF-RU-I6xD-NV9l_g . I've added this issue as a subtopic - we can then probably close this issue. See also: solid/solid-oidc#19 for Solid OIDC

Thanks for this, @NSeydoux. Can I please get a reference to these test reports?
