Thank you for your rapid response, Yoav. Indeed I'm working on the spec draft (for signals and developers), a demo (to facilitate obtaining developer interest), and we have been soliciting interest in this feature in several places. This feature has obtained some positive attention from the hls.js community already due to the potential reduction in transmux steps to play HLS mpeg2-ts content in MSE.
I'll reply further on this thread once I have stronger signals, soon I expect.
