How should the industry tackle such issues?

(Open to suggestions about a more informative title.)

I reported this following issue to the Noto project earlier:

https://github.com/googlefonts/noto-fonts/issues/1761
GUNJALA GONDI VIRAMA behaves inconsistently with the Unicode Standard’s current definition

It’s quite a typical situation. Font producers find something they need to represent and just go ahead and make their fonts to show it, without considering the impact on character identities and text interchange. The industry needs to have a more systematic solution.

This issue is meant to be an invite to some general discussions.
