Any reason to not add asynchronous sink version of boost::log::add_file_log?

The boost::log::add_file_log function in <boost/log/utility/setup/file.hpp>
is a nice function for setting up a file sink. I had been using it and
needed to switch from a synchronous frontend to an asynchronous one. But
the sink returned is synchronous.

Is there any reason to not add a version of the function which creates and
returns an asynchronous frontend? Perhaps called something like
add_async_file_log?
