This one is a request from Patreon patron @hynek since I gesture vaguely and mumble about "framework builds" every time someone mentions a tool that builds and installs Python that supports the mac.
In this post, I continue to mumble and gesture vaguely, because it's hard to give a super precise answer to why this build structure is necessary! But hopefully this will contextualize *why* mac developers want this despite the lack of a precise, exact "this one feature needs it" use case.
