It would be fairly quick and easy for google to add support for font-language-override

Supporting font-language override would not only increase spec compliance, it would be the path of least effort

I am not sure why font-language-override is really needed, can’t a developer simply define a span with another language tag [the one which behavior one wants to mimic]? Won’t the end result be the same ?

Depending on complex mappings from @lang to OpenType lang is a lot of work, currently being done for you by font designers. This is a duplication of effort and a maintenance burden; just support font-language-override. It is there for a reason.

OpenType maintains its own language tag system where the mappings in most cases are 1:1 and in some cases are n:1, but I wouldn’t consider it a complex mapping – as far as user is concerned, there is always a straightforward mapping from a content language tag to the OT language tag. Changing the content language tag, e.g. by defining a span with a different tag, should do the trick.
