Are you willing to wait for 2 or 3 years to elapse to get an algorithm written into a CSS spec, get it tested, and move that spec to at least PR or REC before moving forward on VTT? > > We can wait if there's progress (not with REC, but we don't need it for REC). we can’t go to Rec with the default being something that’s underspecified and unimplemented, and we are way past needing to go to Rec. > > An alternative would be to pick up your algorithm from TTML for WebVTT as well.
