I suggest lots of things of python-ideas that I would probably oppose
if they ever made it as far as python-dev - enabling that kind of
speculative freedom is a large part of *why* we have a brainstorming
list.

For me, type annotations fall into the same category in practice as
metaclasses and structural linters: if you're still asking yourself
the question "Do I need one?" the answer is an emphatic "No". They're
tools designed to solve particular problems, so you reach for them
when you have those problems, rather than as a matter of course.

Cheers,
Nick.
