@sobolevn can please take a look)

* Use of string literal types or type comments
* Use of ``typing.TYPE_CHECKING``
* Use of ``from __future__ import annotations`` (:pep:`563`)
(This directive has been declared deprecated since Python 3.14, and is expected to be removed in a future version of Python)

Maybe mention PEP 649 or PEP 749 explicitly here? There were quite a few discussions regarding deferred annotations, I suspect some documentation users may struggle to find the final outcome:)

But also, given that 3.14 is a pre-release, maybe it's better to wait until we actually have 3.14.0 released. While extremely unlikely, things may still change, and this deprecation may get deferred again.

In the future we will add notes here about __annotate__ and more future plans.
