I guess we could try setting MAC_OS_X_VERSION_MAX_ALLOWED explicitly, but unlike MACOSX_DEPLOYMENT_TARGET, it isn't picked up from the environment by the compiler driver, so a lot of ports would require special handling to get it into the CPPFLAGS.

I don't know if I'm the author of the mail you're thinking of, but I've surely commented on this matter before. It's Jeremy Huddleston Sequoia's work on master I was referring to.

I haven't tested that work. But at least with MacPorts 2.4.1 I perceived that not having an SDK matching the running OS version would be a problem for some ports, so I didn't update our OS X 10.11 buildbot worker from Xcode 7 to 8, and similarly I won't update our macOS 10.12 worker from Xcode 8 to 9.
