Try to work on solving the problem and identify the use cases. I don't
think the standard will cause a major problem, we should be able to make
the relevant parts of your patch match the standard.
That's one reason to work on it as an extension first: we can get a
better sense of the problem space and various use cases without worrying
about violating any standard. Then, as you need specific backend support
(e.g. special syntax), we can take the standards more seriously.
