This proposal seems like trying to reverse engineer a normalization form into an encoding form, which at face value having an encoding form that doesn't even technically support denormalized forms sounds like a good thing until you start to read the details on all of the normalization forms and get into the weeds and edge cases of why normal forms are locale specific and why normal forms are so complex even beyond that that you start to question if "single canonical binary encoding for character sequences" is at all possible and I think you start to appreciate why the normal forms are algorithms at a higher level above the raw binary encoding rather than attempted to be built into the binary encoding form.
