Thanks for pointing out that variable. While release notes do confirm
the 11.0 on ARM vs. 10.16 on Intel defaults:

  "The system ProductVersion is reported as 11.0 only on the Developer
   Transition Kit at this time. Existing Mac systems will temporarily
   report the value as 10.16."

..SYSTEM_VERSION_COMPAT=1 does indeed make the DTK report 10.16. The
reverse isn't true; setting SYSTEM_VERSION_COMPAT=0 on Intel does not
yield 11.0.
