I suspect you’re not involved in contemporary record making. Like it or not, clipping is a technique and a color that producers, mixers, and mastering engineers all choose to impart for aesthetic and technical reasons. It has it’s uses.
If your proposal were passed all that would be left for consideration would be a handful lame DSD jazz records from those hi-fi enthusiasts who are disconnected from the reality around how most records are made these days.

What RIAA should do is promote universal use of ReplayGain across digital distribution platforms. That way people can manage relative volume as desired without the need to corrupt the audio. They could make money with a signed tag certifying the mix meets quality standards.
The ideal solution would be to distribute high dynamic range audio with metadata to configure optional playback-time dynamic range compression for noisy listening environments or weak playback equipment.
Or make a sound format (like video containers) that could have two separate mixes of a track.
