Comment (by mcsf):

 In terms of what should be ''correct'', I suspect we need a filter for
 `get_attributes` like the one in the patch.

 Further, since client-side hooks can be applied to blocks indiscriminately
 based on specific `supports` rules, it should be possible on the server to
 hook into blocks based on the same rules. That way, a plugin can make sure
 that its client-side extensions don't harm server-side expectations of
 blocks. However, AFAIK, there is no current server-side knowledge of a
 block type's `supports`.

 Regardless of what we decide for SSR documentation, it seems that a patch
 for this should cover `supports` as well.
