But since Python 3.8, Python doesn't use this \"Multi-Phase Initialization\" API and I failed to find any user in 3rd party code.\n\nI propose to remove this API in Python 3.14 without any deprecation since the feature was [provisional](https://docs.python.org/dev/glossary.html#term-provisional-API) and it's a private API.\n\nProvisional:\n\n\u003e A provisional API is one which has been **deliberately excluded** from the standard library’s **backwards compatibility guarantees**.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-129034\n* gh-129048\n* gh-137379\n* gh-137382\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/vstinner","@type":"Person","name":"vstinner"},"datePublished":"2025-01-19T22:03:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/129033/cpython/issues/129033"}
