What about spread spectrum modes? Supposedly such a

Doesn't work that way. It's more like "QRM to almost all other
users".
There was a clear discussion of this by KE3Z (IIRC) here some years
back. The interference potential of SS on HF was clearly
demonstrated.
I can google it for you if you want.
How does that compare to BPL? BPL is allowed on the ham bands.
