Let me dispel that misconception.

Here is the ConstBufferSequence concept definition:

https://www.boost.org/doc/libs/1_36_0/doc/html/boost_asio/reference/ConstBufferSequence.html

This is the 2013 version of the library, seven years before the `concept`

ConvertibleToConstBuffer (also located on the page)
