Feature or enhancement

Proposal:

It was deprecated in 3.13 but there was no removal notice in the docs: see #105570 and #105780. I don't know whether it's better to delay it a bit more just to have a deprecation notice or to first add a deprecation notice for 3.13 and 3.14, but still remove it in 3.15.

   there was no removal notice in the docs

   What do you mean exactly? #105780 added detailed deprecation notes to the API reference for typing.TypedDict and to "What's new in Python 3.13". It also included a NEWS entry noting the deprecation, and added DeprecationWarnings at runtime.

   I meant in the pending deprecation section (which had the other removal notices)

   I see. Personally I think we've given enough notice for this removal in enough places, but I also don't mind if you want to add some notes there too and extend the deprecation period. It's not a huge maintenance burden for that code to hang around for a bit longer.

   How about this:

   • Add entries in the "pending deprecation" section for 3.13 and 3.14
   • Go with the removal for 3.15.

   I just wanted to be sure it was fine on your side as you're a codeowner of typing.py. I also feel it's a bit weird that we don't remove the TypedDict kw syntax but remove the NamedTuple kw syntax so I'm all for the removal in 3.15 (it simplifies the code quite a lot)

   Yeah that plan sounds fine by me! I don't think the syntax that was deprecated was widely used at all, and I think the pending removal was pretty well signalled

   I'm also fine with getting rid of this (and the NamedTuple equivalent) now.

   See #133822 for the NamedTuple equivalent. I'll do the TypedDict one tomorrow.
