Adding some more context here - when initializing the config shard in the shard registry, we don't necessarily know the config server's UUID (if we are on a shard, we only know the connection string and if we are on a config server secondary we haven't necessarily seen the shard identity yet). In this ticket, we need to decide how we want to handle this case.

It seems likely that having the config shard data in the shard registry missing the UUID would be okay in the vast majority of cases, the only question is whether someone (especially on the config server) would expect this to be initialized at some point in the future.
