I fully agree it's inefficient, but there are two massive issues with trying to change that model.
1. Bandwidth. With a DVR, (especially the new whole home dvr's), it's not an issue to stream live and/or recorded TV to four TV's in the home, all in HD. Further, if you have Satellite, you can do this from anywhere in the U.S. (just need electricity and a dish). However, with an IPTV solution, you'll need lots of bandwidth (i.e., at least 50Mbps +) to match the current capability of what you get right now from a whole home DVR. Also, streaming 100% of TV viewing is also an issue for bandwidth caps. If you are lucky enough to have Google Fiber, then this isn't an issue, but for most of us this is a big issue.
2. Content rights. The content providers don't like DVR's since they want to charge for each viewing, but they can't stop local DVR's. However, for now I think online DVR's are not legal and the only way the content providers will allow online DVR's if they charge more for accessing the content multiple times.
I think Microsoft realized these two issues as being too large to overcome anytime soon, so they gave in and just provided and HDMI loop and figure it's best to just let you continue to use your cable or satellite STB.
