Our CI system uses publicly available build infrastructure from GitHub, which only offers build machines running current versions of macOS, currently 10.14 and later I think.

Designing our own CI build infrastructure and hosting it ourselves is possible, and then we could offer it on as many macOS versions as we like. But the work to do this has not been completed, nor really begun. See other recent mailing list thread.
