Not literal rot, but as the operating system and developer tools move on, it gets more and more difficult to maintain older software that is not under active development.

Subports are just an organizational tool. Once in the index, the ports created with the `subport` command are basically equivalent to those created at the "top level" of the portfiles. Replacing subports works fine.

This is not our general attitude towards this matter.

We prefer users not be allowed to choose their dependencies unless there's a good reason, such as API/ABI incompatibilities, or if the dependencies would take a very long time to build.

(For instance, if llvm-* didn't take so long to build, we'd probably make ld64 and cctools rely on a single version instead of providing variants.)

A buildslave will not provide archives that a user could not compile themselves.
