Bug#36835 is not specific to macOS, so if we allow multiple font
backends on Posix platforms, where this bug happens, why avoid that on
macOS?

Of course, I'd prefer that we fixed that bug, and sooner rather than
later, but other than that, having all modern platforms support and
use HarfBuzz is IMO an important development goal for Emacs, certainly
if the alternative is proprietary software.

Thanks.
