"showstopper for a lot of people" People trying to do what, exactly? And how would existing ham users benefit by having the bands taken over by those commercial activities that the FCC regulates under other parts? There are multiple roadblocks: FCC part 97.113(A) prohibited transmissions contains: "(5) Communications, on a regular basis, which could reasonably be furnished alternatively through other radio services." So... if all you're trying to do is replicate a wirelessISP or satellite internet service, but do it for free on the ham bands, well, that's illegal in and of itself aside from encryption. This part of the law has occasionally caused controversy for the RC airplane people on the 6M band, the "text email service for sailboats" people on HF, couple others. And if you live near the border of a country or have impressive range there's part 97.117. And there are interesting regulations for 3rd party traffic across international boundaries. And there are pecuniary interest regulations, so no doing work or getting paid for it or having money change hands except under relatively weird and limited forms. Its not as simple as crossing out a couple words in 97.113(A)(4) that prevent "messages encoded for the purpose of obscuring their meaning". That alone will not magically let wireless ISPs offer service pretending to be ham radio.
