It's not that much extra work to compile, the extra work comes from the maintenance and feature requests. By not shipping the binary directly I am defending my time until other contributors want to step up and maintain things. I am one person with limited time and I don't want to spend all of it in front of a computer
Yes you use them through a wheel. If you have specific questions on packaging and how to use things lets move it over to the discussions/issues in the repo itself so it can be more broadly accessible to more people and we can make the packaging of the library as useful as possible
