I don't think that it's really useful to deprecate this behavior: it's fine to keep it. The ``PyObject_DelAttr()`` function is just implemented as a macro passing *NULL*:\r\n\r\n```c\r\n#define  PyObject_DelAttr(O, A) PyObject_SetAttr((O), (A), NULL)\r\n```\r\n\r\n\u003c!-- gh-linked-prs --\u003e\r\n### Linked PRs\r\n* gh-105374\r\n* gh-105394\r\n* gh-105395\r\n* gh-106537\r\n* gh-106538\r\n* gh-106540\r\n* gh-106675\r\n\u003c!-- /gh-linked-prs --\u003e\r\n","author":{"url":"https://github.com/vstinner","@type":"Person","name":"vstinner"},"datePublished":"2023-06-06T13:02:48.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/105373/cpython/issues/105373"}
