The requestIdleCallback spec has been converted to respec (many thanks to Philippe for converting the initial spec over to respec) and can be viewed at https://w3c.github.io/requestidlecallback/.
We would be very interested in any getting any feedback and / or issues before moving towards first publication. Please feel free to create issues and / or pull requests on github repository at https://github.com/w3c/requestidlecallback. Cheers, Ross
