You stall have CA (DT) classed TV stations broadcasting from channels 2 - 6 on VHF low band in the USA. Few today, but still some, like WDTV, CH5, (And yes, RF CH5.), in Clarksburg, WV is one of them. Yet, back in the 70's, the FCC let commercial two-way dispatch station exist in what's know to be the UHF "T" band from 470MHz - 512MHz, or the lower portion of the UHF TV band, if a UHF TV station didn't exist in that city of operation. I do agree though, that better spectrum usage from 54MHz - 88MHz could be had. There's still R/C (Voiceless.), usage around 74MHz. The big problem that's feared though is Sporadic "E" interference that this part of VHF exhibits. It's just the nature of the beast. (To take a cue from April Wine tunage.) Japan certainly doesn't seem to have a problem with FM stations there, as evidence of radios meant for that market that still make their way here. Certainly, would be good down there for lower powered stuff, like more LPFM, translators, and non-commercial stations under 1kW. Sure... They'll still skip in the Summer, but not like a 50kW station. Hmmmmmmmm... Does anyone know just what the N.A.B's stance is on 54MHz - 88MHz? I wonder... Anyway, my take, and $0.02 worth.
