dealing with build, dealing with continuous integration, continuous deployment, source control, etc. It's not like build systems and source control were invented after 2000. Or basic CI/CD practices for that matter (though perhaps not as automated as today). However, in the case of build systems, they have been reinvented a dozen times annually since then (mostly make clones).
