Keep in mind that to continue automatic testing on older Apple platforms you have to run it on older Macs, which might not be available on the market anymore. CI/CD jobs are usually ran on mac minis, and if there are no more new mac minis with macOS older than Catalina, then it would not be possible to test against it.
