8VSB was chosen because it allowed conventional translators top be used. Reality, who knows. In any event, the jury is still out on SFN working with 8VSB.
Broadcasting is more about politics than engineering.

That would compact the frequency needs such that LTE style broadband could be done in UHF instead of breaking up the GPS signal. SFN requires sufficiently good timing... but last time I looked at the ATSC SFN spec they got the fundamentals completely wrong, doable but overspeced due to the missunderstandings.
