Status: Available
This extension will require work in the ANGLE shader translator which could be done in parallel to supporting it in Blink.

Owner: bajones@chromium.org
I've already got the Blink-side code for this ready (https://codereview.chromium.org/171263004/) but am waiting till the ANGLE code is ready to do the rest of the implementation. We'll also need a conformance test for the extension, but that probably requires a working implementation first.

Vladimir from Mozilla has an ANGLE patch ready to go, it sounds like. (See link in OP) Not sure what the status is there, we may be able to jump in an help land it if it hasn't already.
Please also add this support to ppapi.
