If you think you'll be able to divine that if and only if the documentation is entirely written by a human, then I'm afraid I'll have to disappoint you: no language has ever evolved strictly according to the initial plan of their authors. Nor has any author's strongly held belief about the future ever panned out the way they thought. Nor has the documentation ever held the immutable future of the language, even when fully human generated (which essentially zero languages have, even before AI).

The way to find out if a language is suitable for your needs is not to demand, in an entitled way, that the author perform an act for you. It is to (a) ask the author politely; or, failing that, (b) to examine it yourself (or ask Fable to evaluate it, using tokens you paid for).

This particular language, further, is Apache 2.0 licensed. If it's not working for you, fix it. Jesus.
