Some browsers are still doing "transitional" UTS#46, it is time
they move on.  In up to date releases:

    Firefox:	Already UTS#46 non-transitional
    Safari:	Already UTS#46 non-transitional
    Chrome:	Still broken:
		https://bugs.chromium.org/p/chromium/issues/detail?id=505262
		https://bugs.chromium.org/p/chromium/issues/detail?id=61328

Postfix and Exim have also moved on to UTS#46 non-transitional.

Just move on to non-transitional UTS#46.
