ie, nothing failed, but the given id eitehr doesn't below to the given protocol, or fetched successfully but its data belongs to a different protocol.
vs raising exceptions for fetches that fail or error, eg network connection problems, Web got HTML with microformats2 but no h-entry, ActivityPub got non-AS2, etc.
used in Protocol.for_id: when a given Protocol's fetch doesn't work, we move on and try the next protocol _if_ it returned False (ie wasn't fetchable with that protocol, but we fail fast if it raises an exception (ie fetch failed).
tried a bunch of other more sophisticated ways to do this in snarfed/webutil@280a93e092 (plus snarfed/webutil@6cb9c1f719), tried a custom repeated property class that acted like a set instead of a list, but couldn't get it to work reliably or compatibly enough.
