Also, the fact that no-one raised this issue during the whole time the

Guido (who of all of us should be most aware of what is and isn't
acceptable use of annotations in the stdlib) approved the PEP,
suggests to me that this isn't that big a deal.
Hi, I asked about this in the first posting of the PEP and agree with Chris.

There is definitely a passive bias towards using types with dataclasses in that
the Eric (the author) doesn't appear to want an example without them in the
pep/docs.
It seems that typing proponents are sufficiently enamored with them that they
can't imagine anyone else feeling differently, haha.
Personally, I wouldn't use types with Python unless I was leading a large
project with a large team of folks with different levels of experience. That's
where types shine, and those folks might be better served by Java or Kotlin.
So we hearing that "types are optional" while the docs may imply the opposite.
Liked the ellipsis since None is often used as a sentinel value and an extra
import is a drag.
