I get the reason why fractional frame rates are required for NTSC equipment/broadcasts, but are they required under ATSC?

If so, why? One of the primary points of developing ATSC was to revamp the bandwidth to accommodate for HD video, but wouldn’t that have given them the opportunity to solve the problem that created the need for fractional frame rates to begin with?

I understand that ATSC can support fractional rates, but does it requirement them to broadcast or display?
