Sub-Optiomal type hints in ConversationHandler

[klim-neumann]

Steps to Reproduce

1. Сreate an instance of the CallbackQueryHandler class
2. Create an instance of the ConversationHandler class with entry_points that contains the instance from the first step

Expected behaviour

Type checking should pass without errors

Actual behaviour

Type checking throws an error:

Argument of type "list[CallbackQueryHandler[DEFAULT_TYPE]]" cannot be assigned to parameter "entry_points" of type "List[BaseHandler[Update, CCT@ConversationHandler]]"

Operating System

MacOS 12.6.5

Version of Python, python-telegram-bot & dependencies

python-telegram-bot 20.2
Bot API 6.6
Python 3.11.2 (main, Apr 15 2023, 18:09:35) [Clang 14.0.0 (clang-1400.0.29.202)]

Relevant log output

No response

Additional Context

ConversationHandler entry_points should be Sequence[BaseHandler[Update, CCT]] instead of List[BaseHandler[Update, CCT]]?

Hi. To clarify: This is not about runtime behavior but about sub-optimal type hints, right?

[klim-neumann]

yes, that's right.

Okay. Thanks for pointing it out. Overhauling CH is a big item on the roadmap.
I'm adding it to the (long) list in #2770 and will close this issue in favor of #2770 :)
