Totally agree, moreover here the window of inconsistency can be tuned by pinging the invalidation connection as often as needed. However I'm sure we better have excellent documentation about best practice, like: if the invalidation connection is gone, the cache should be flushed to avoid stale reads, and things like that. Notably the reverse condition is ok: if the data connection is gone, one can reconnect and enable again redirection to the old client ID :-D
