the Great Tooling Revolution

[Michael Dyck]

In the March 24 meeting notes (e.g.,
https://github.com/rwaldron/tc39-notes/blob/master/es6/2015-03/mar-24.md ),
there's the line:
     DD: once the great tooling revolution arrives, there will be a live
         GitHub version of the spec that implementers consult.
but I don't see any discussion of this in the meeting notes or in
es-discuss. Could someone describe the plan?
