We never really allowed instances here and deprecated it since NumPy 1.21 (it just failed completely in 1.21.0).

"default" could use some clarification. I assume some of the outdate alternate (example?) types are deprecated?

Hmmm, tried to make it more specific. Basically, I still allow the singleton instances (and things that are equivalent to it). But really, we only enforce the DType (class/type) anyway, and are just generous about allowing those.

FWIW the new wording LGTM and matches the terminology (i.e. "canonical") in the relevant NEPs
We still allow the "singleton" instances (which mainly applies to our own dtypes), mainly because it wouldn't really do much good to disallow them, even if they are not specific (since we don't enforce the byte-order, but we never return non-native byte order for example).
