Shorter me: this is why I keep asking people who want flattening to
actually provide an example of where flattening is useful, that isn't
(a) assimilation, (b) a result of weird language semantics from some
non-JS language, or (c) an authoring error.

So far, I haven't gotten one!  Every concrete example I've received so
far just shows off assimilation, or a misunderstanding of what JS
promises/futures do.  :/
