I'll take it one step farther. The library should:

* Default to compilation into a static or dynamic lib, e.g. libboost_deflate.o
* Compile header-only, by defining BOOST_DEFLATE_HEADER_ONLY
* Require only C++11
* Compile without the rest of Boost (i.e. no dependencies), by defining
  BOOST_DEFLATE_STANDALONE. In this configuration, C++17 or later
  will be required. The boost:: namespace will remain.
* Configurably support C++ equivalents of Boost types such as
string_view and optional.

All of my new libraries follow this pattern. To assist in building
such libraries, I have created a repository "library_template" which
has a trivial function, that serves as a template which anyone can
clone to form the starting point of a Boost library meeting these
requirements. It has Bjam and Boost-compatible CMake support, tests,
examples, coverage, sanitizers, CI (travis, appveyor, azure), and
working badges:

Yes thank you, this is precisely what the OP was asking. I agree
having convenience functions is great, something like this too:

    std::string compress( string_view s );
