lowest_layer() is deprecated in boost::beast, replaced by boost::beast::get_lowest_layer(), but still in use by boost::asio:ssl::stream

Hi,

The boost libraries beast and asio seem to disagree on whether a socket/str=
eam should offer the lowest_layer() method or not. Boost::beast::tcp_stream=
 has only private versions of this method and the associated typedef lowest=
_layer_type, while e.g. boost::asio::ssl::stream still requires this method=
. The replacement get_lowest_layer() is only offered in beast.

For  boost::asio::ssl::stream this is handled by boost::beast::tcp_stream d=
eclaring boost::asio::ssl::stream as friend, so offering access to lowest_l=
ayer().

But I have my own ssl stream, based on a different SSL library than openssl=
, and this stream class is also (because it is based on boost::asio::ssl::s=
tream) dependant on lowest_layer().

I think, boost::beast and boost::asio should agree on whether to deprecate =
lowest_layer() and offer get_lowest_layer(), or not.
