They might be able to fix HDMI or a work around fix. Why not have one wire in the HDMI be analog then use that info to over lay Closed Caption. They could have used another wire for Closed Caption like another RCA jack?
Any way I do not see HDMI being fixed at all. Reason for that they always updating HDMI from 1.0. 1.2. 1.3. 1.3a and so on.
If they did fix it and let's say it got fixed in 1.4 you would need a DVD player that was HDMI 1.4 and a TV set that was 1.4
The only real fix I can see happening with the government is have hard encoding of Closed Caption.
