current mysql protocol responses return field names, column aliases, table names, field types and even catalog "def". All that fat data transfer makes network traffic bloated, clients more expensive, etc. Most of database clients may already know what they are reading anyway. 

Prepared statements are not helping here, as they don't support dynamic nature of various applications - on systems with thousands of systems current prepared statement framework falls short early. 

Making protocol cheaper (guided by client flag) would be an easy step towards great future, etc.

How to repeat:
check out traffic of high-throughput OLTP systems that do lots of queries. oh no, thats ugly!

Suggested fix:
have zero-metadata protocol option

Having a lighter protocol could make sense if that is optional, just as you described.

Verified feature request.
