I'm not even talking about compilers though... all I want is a baseline standard that I can point to and say: "Here. This right here is where it says that 'curl' and 'wget' shall be available and in $PATH."

And some simple command for any Linux distro or macOS to install everything necessary to adhere to that standard, or a distro that conforms with that standard in the first place.

That is "Shell & Utilities", however curl and wget haven't yet gotten POSIX status.
