ApplicationsResource also allows calls of the format /apps/{appId} for specific applications, we would want to cover this Target type here too. If we don't want to introduce more Target types it could roll up into FullFetch.

I did not include this on purpose, as majority of clients will do full/delta registry fetch. If we would like to include this as well, we can add another target type.

That makes sense too. We did add a feature to the client recently that allows clients to be configured to change it's periodic fetch from a full_all/delta_all pattern to be always full_single_app, so I just don't want this feature to become a backdoor to get around the rateLimiter.

I will add apps/<app_id> to the full fetch bucket.
