That's a controlled environment, though; Samsung almost certainly creates a customized build of Chromium for its TVs and can simply keep NaCl enabled if it wishes. They aren't beholden to the same policies that apply to the consumer Chrome releases.
The problem is that you eventually end up stuck with an ancient version of Chromium without security fixes and incompatible with websites that use newer browser features.

Samsung can't even keep their flagship phones up to date, their TVs are not going to be kept updated regardless of what Google does with Chrome...
