My workarounds for older versions of macOS are contained inside those `if {${os.major} <= 15}` conditionals.

Ideally you wouldn't have to use any (and the portfiles would all be declarative) - that's not really possible now, but I think needing them is a good indication of areas where we should enhance MacPorts base to make it (eventually) possible to not need them.

For os.major stuff, I think there have been some proposals for range syntax, just none have been implemented yet.
