| well h.264 is an interesting question. while often thought of as a very compressed long GOP format, it can be iframe, 10/12+ bits, 4:2:2 and 4:4:4 with a high enough bit rate to be near lossless.
while the format you propose would like to directly avoid any patent encumbered technology, having it be open enough that a suitable h.264/5 codec could be added might well turn out to be a critical item in getting wider usage. another developer could bring in a suitable codec component.
ditto ProRes as odd as that might sound given its widespread use in cameras and recorders.

The number one thing I would like to see is for the container to also be the app to play the spot, so that each spot can be played on any system without installing any other apps (and I get why this might be too hard or it would have already happened).
However, this would sort of future proof the movies. There is nothing worse than finding a movie and then not being able to play it on newer systems for whatever reason.
Unfortunately, I do not think that would future-proof the movies. Perhaps the opposite.
How often has an OS update made a program stop working? What if now your movies stopped working? This is another beef I have with QuickTime - since programs use the QuickTime service to read the files, a system update could eliminate a codec you had been using and break your files in every program.
Since OpenEXR has an open source library, even if your software has been broken by an OS update, you just have to get another program built with the latest OS in mind.
Also, these movies would not be cross-platform as generally an app is made for one particular operating system. (Maybe Java?)
I understand the desire to have a file you can send to people and be guaranteed they could play it back without needing to install anything, but I don't think we'll get there any time soon. The best we can do is have a format like MP4 with H.264 which is so ubiquitous that virtually anyone with a web browser should be able to play it. But that format is no good for production, so we need POM.
