2023-11-17 - FCC Removes Symbol Rate Limitations on US Amateur Radio HF Bands, Next Up - Removing Symbol Rate Limitations on the US Amateur Radio VHF and UHF Bands; the FCC Requests Comments
I think one better argument for removing the symbol rates is that for some modes (ie am and fm) your transmitted signal bandwidth is the same no matter what audio is going into the mic. The majority of VHF and UHF is fm, and even ssb is limited in bandwidth. So letting hams transmit up to the full audio bandwidth makes sense to me.
