Delivery via MPEG-2 is not a use case. It's a potential solution for
addressing a use case.

Which browsers currently implement MPEG-2 without DRM in HTML5 video?
Which one intend to? What about with DRM?

Which content providers currently serve MPEG-2 in an HTML5-based
player? Which ones intend to? What about with DRM? To address what use
cases? Why with a codec that needs more bandwidth than either H.264 or
VP8 and that comes with a less favorable licensing regime?
