This could be useful when optimizing system performance.

By size, do you mean the size of a message once it it serialized?

Yes, if that means the same as the throughput of a publisher if the publisher published that message.

Just want to confirm: Is it not possible at this stage? Will it be supported later?

Currently there is no API to determine the wire size of a message. And it isn't planned to implement that feature.
