And then there are truly trivial removals like the "failUnless" or "SafeConfigParser" aliases. I don't see a good reason to remove those -- they could stay deprecated forever.
This part I do not agree with. In 3.10, there are 15 fail* and assert* aliases with a messy overlap pattern. https://docs.python.org/3/library/unittest.html#deprecated-aliases This is 15 unneeded names that appear in the doc, the index, vars(), dir(), TestCase.__dict__ listings, completion lists, etc.
Well, dir(), vars(), __dict__ and similar are already unpleasant -- ever since they started listing dunder methods, quite a long time ago. But we could improve completion, docs and other cases that can filter the list. How about adding a __deprecated__ attribute with a list of names that tab completion should skip?
No. There would be less, not more reason to censor such names. Names that remain forever so that they can be used forever need to be listed forever. My background point is that there is a real cost to keeping obsolete names forever. I appear to see that cost as higher than you do. -- Terry Jan Reedy
