Speculation on this is tough and has IMO really stymied standards efforts.
The best way to know is to put something we think is a good effort out
there for real use and get feedback.  We're much better of when we can base
decisions on data rather than guesswork.  Ideally we could reasonably
prolyfill the API surface, but for low level primitives, this is tricky.
Is there any way we can, even if under the covers it didn't have quite the
same implications?  If so, let's try.  If not, it seems next best would be
to get in in a browser or two ASAP and leave it behind a flag until we can
collect some.  In not sure how negatively this would affect other things
like service workers in terms of delays and frustrations though.
