poets will finally be able to preserve whitespace as they write

Awesome! And it sounds as if the new editing interface may also make other poetry-formatting challenges easier, such as allowing writers or editors to identify individual lines, not just paragraphs, for special formatting (e.g. wrapping on indent on smaller screens). Regardless, thanks for continuing to take the WordPress motto seriously and considering the needs of poetry bloggers, an economically insignificant user-group if there ever was one.
