There are also some practical issues with trying to distribute software
using some deprecated Cocoa APIs or weak linked syscalls. The pythonmac-sig
thead I linked to earlier has pointers to how to flare those up if one ever
needs to distribute Python to a specific macOS version target range while
compiling on a newer macOS.
It would be nice to do more things the Apple way, including porting to
modern runtime feature availability check cascades of the Cocoa APIs and
using the Apple provided system Frameworks. This seems like a rather major
workload and should be targeting 3.8. I'm willing to participate in that
The availability of syscalls across targets when cross-compiling for an
older target is a more generic build system problem and I'm not sure if
Python should do anything other than just document it being a thing. I'm
personally fine patching pyconfig.h after running the configure script for
this special case.
As suggested on pythonmac-sig, I'd like to see 10.11 get chosen as the
macOS to build on as it provides a decent balance between hardware
compatibility and being new(er).
