Question about Schema Development Timeline

To whom it may concern,
I am taking a look at the http://health-lifesci.webschemas.org/ schema,
which seems quite powerful and it appears to be in development.

I am curious what the timeline is for this schema to get approved for
sponsorship by groups like Google, Yahoo!, etc.? As well, I am curious what
can be done with schemas that are only in development.

Thanks for the support!
Cheers,
Dan Guo
