Yes, it is brutally asserting the definitions and nothing else.

Yes. The one benefit that I see is that it does not require introducing 
a vocabulary that would "reserve" some URIs.

Damn, I sometimes used bold face T as if it meant the set of all terms, 
while it is in fact defined as the set of RDF-star triples.

α should be defined on "B ⋃ T ∖ Gnd".
There is an unfortunate copy-paste error before the colon of the 1st 
paragraph in section "az-Satisfaction"("𝓘[α](t) = : T → Δ" should be 
"𝓘[α]: T → Δ" and the second item of the first bullet list of this 
section should have "B ⋃ T ∖ Gnd" instead of "T ⋃ Gnd".

I'll correct that.
