该peer chaincode invoke命令不接受版本标志：
$ peer chaincode invoke --help
Invoke the specified chaincode. It will try to commit the endorsed transaction to the network.
Usage:
peer chaincode invoke [flags]
Flags:
-C, --channelID string The channel on which this command should be executed
--connectionProfile string Connection profile that provides the necessary connection information for the network. Note: currently only supported for providing peer connection information
-c, --ctor string Constructor message for the chaincode in JSON format (default "{}")
-h, --help help for invoke
-n, --name string Name of the chaincode
--peerAddresses stringArray The addresses of the peers to connect to
--tlsRootCertFiles stringArray If TLS is enabled, the paths to the TLS root cert files of the peers to connect to. The order and number of certs specified should match the --peerAddresses flag
--waitForEvent Whether to wait for the event from each peer's deliver filtered service signifying that the 'invoke' transaction has been committed successfully
--waitForEventTimeout duration Time to wait for the event from each peer's deliver filtered service signifying that the 'invoke' transaction has been committed successfully (default 30s)
Global Flags:
--cafile string Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint
--certfile string Path to file containing PEM-encoded X509 public key to use for mutual TLS communication with the orderer endpoint
--clientauth Use mutual TLS when communicating with the orderer endpoint
--connTimeout duration Timeout for client to connect (default 3s)
--keyfile string Path to file containing PEM-encoded private key to use for mutual TLS communication with the orderer endpoint
--logging-level string Default logging level and overrides, see core.yaml for full syntax
-o, --orderer string Ordering service endpoint
--ordererTLSHostnameOverride string The hostname override to use when validating the TLS connection to the orderer.
--tls Use TLS when communicating with the orderer endpoint
--transient string Transient map of arguments in JSON encoding
根据对此问题的评论，缺少版本选项是故意的。
但是，如果我有客户端使用各种接口版本，我是否也不想维护旧的链代码版本来接受那些旧的客户端数据格式？
我知道我可以在发送invoke到对等方之前过滤服务器端程序中的客户端数据，但似乎允许多个链代码版本将允许更大的灵活性。我们可以期待未来某个时候的版本选项chaincode invoke吗？
