To me, this is the best use of this information.  Secondary would be if people wanted to do a target_supports, it would be more clear to the untrained why it was done in the first place.

Thanks for the guidance.
I learned how to make a better description for a test case. :-)

And thanks for the approval,
the revised patch is now applied as Rev. 205625:
