Now you can develop the lib in the direction that you need and you have people on payroll that do it, this seems like good risk management.

Author here: I think you are projecting quite a bit. We do in fact hire a lot of people who maintain things, and even pay quite a lot for OSS development on things like the compiler and libraries we care about. But we still have business objectives to achieve, and sometimes it makes more sense to write things that better suit our needs.
