Etags are not really much simpler than a metadata versioning sync protocol, and they are a lot less efficient.   Having to fetch the whole directory for every directory that contains a change is expensive, both for the server and the client, unless changes are infrequent.   And because the server is the sole source of truth, it's a lot more fragile.
