Yeah, I don't manage dev dependencies for projects in home-brew, just software for which I am a mere user. I probably wouldn't use apt and friends for those, either—not directly on my workstation anyway, maybe in some pinned-OS-version VM—unless my workstation happened to be identical to my deploy target and was guaranteed to stay that way. For a macOS build for C or C++ or anything along those lines, I'd probably vendor dependencies.
