 Description   

Quoth the arch guide:

If the metadata has a different config version than the downstream node's config version, then the metadata is ignored until a reconfig command is received that synchronizes the config versions.

I think this is no longer true. The downstream node now uses another member's ReplSetMetadata even if their config versions are different.
