I would be careful here. People arr known to use private functions of importlib even in private projects because sometimes there is not better replacement so I do not think we need to really remove it without a notificationat least. So please create a NEWS entry.

Thanks. I've added a NEWS entry. On the broader concern: before proposing this I ran a GitHub code search for importlib._bootstrap._object_name and from importlib._bootstrap import _object_name and found no downstream importers, which is why I scoped the PR to just this symbol. It only rendered an object's qualname for the load_module() deprecation warnings that gh-142205 removed, so it has no remaining caller in or out of the tree that I can find. A code search only reaches public code though, so private users could exist that we will never see.
