I don't see any users of vendor_send_message in this series, so I prefer
it to be dropped and introduced when required.

Also I had a different view on how to introduce this[1]. I would rather
wait until the requirement comes that enables us to make use of it.
Looks like you took parts of it and introduces vendor_send_message
allowing users to send any data which I don't like especially without
knowing how will it be (ab)used.
