   @sijie I am thinking about compatibility tests.
   What is good to test, my idea is:
   1) a new client with "deferred force" MUST NOT be able to write to an old bookie
   2) an old client SHOULD able to read ledgers created with "deferred force" (for the reader we are not changing the LAC protocol, and the bit in metadata is not useful for readers)
   
   apart from these cases, for which I can add test cases in next patches, but not in this (because in this patch nothing is "really" working) I think that existing tests are good tests: new clients which use default LedgerType are able to cooperate with old bookies/clients
   
   Do you have other ideas ?
