I agree with consistency, both for z/OS and our generic way. Grepping for `XFAIL:.*target=` has 101 hits, `UNSUPPORTED:.*target=` 44 hits where 25 are due to zos. 
Could you make a separate review for the existing `UNSUPPORTED` -> `XFAIL` changes? Feel free to assign that patch to me. If you can assign, please leave a link in this review.
