Stating `then()` is something more advanced than `done()` doesn't make much
sense to me.
They're different methods, that serve different purpose, I think they should
be valued on a similar level.

Key thing is that *`then()` is conceptually a `map()`*, and there's
something wrong if just to access the value we have to use `map()`. Second
issue, mentioned already numerous times is not desired (in case of "just
access") error suppression.
