As best as I can calculate, at this point there are 611 Language tags in this package, 632 in the current Working Draft for the ISO/IEC 14496-22, and 635 in the Microsoft OT spec.

Is there a reason this repo tracks the tag registry of the ISO/IEC spec rather than that of the Microsoft OpenType spec?

It seems like ISO/IEC eventually adopts any script, language or feature tags registered by Microsoft, but it takes many months for changes published in the Microsoft specification to bubble through to a release of the ISO/IEC. In the mean time users of fontbakery are getting FAILs for including support for languages that have not yet bubbled through to ISO/IEC.

If we must track the ISO/IEC spec, could we track Working Drafts as well as releases?

Deprecation warning while installing Font Bakery:

DEPRECATION: opentypespec is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559
