Tree shaking with ES imports doesn't seem to work in v2.27.0

Or I am missing something.

This is when using

import format  from 'date-fns/format';

And this is the same when using

import { format }  from 'date-fns';

Seems fine. Have a look at this previous discussion, I think you might just be misunderstanding the webpack bundle analyzer values. #2521 (comment)
