IMHO that is a failed example of "Chuck Moore's stuff". He went down a rabbit hole to an extreme level because that's what he does. His earlier CPU experiments like the 4016 and Shboom were excellent examples of ultra-RISC architectures.

The thing Chuck explored, related to abstraction, which I don't see much in conventional machines was reducing calling overhead. (1 cycle call and intrinsic return on many instructions ie: free return)

Some of the decisions we make today have a lot to do with what happens at the hardware level when we add abstraction. It just costs more than we are prepared to pay so it is avoided ... but for the wrong reason.
