We may want to have one very pinned requirements file (possible managed by one of the auto-bump services 😞 or tools) that we rename to `fully-pinned-v3.6.x.txt` on branching.  We can then use that (exclusively) for tests on the backport branch which should hopefully reduce the amount of dep-only backports we have to do (and provide a useful reference for anyone who wants to get old versions testing again).\r\n\r\n_Originally posted by @tacaswell in https://github.com/matplotlib/matplotlib/issues/22574#issuecomment-1059892443_","author":{"url":"https://github.com/tacaswell","@type":"Person","name":"tacaswell"},"datePublished":"2022-08-03T21:57:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":18},"url":"https://github.com/23548/matplotlib/issues/23548"}
