[$] Python discusses deprecations

Feature deprecations are often controversial, but many projects find itnecessary, or desirable, to lose some of the baggage that has accreted overtime. A mid-November request to get rid of three Python standard librarymodules provides a case in point. It was initially greeted as a good ideasince the modules had been officially deprecated starting withPython 3.6; there are better ways to accomplish theirtasks now. But, of course, removing a module breaks any project that usesit, at least without the project making some, perhaps even trivial,changes. The cost of that is not insignificant, and the value in doing sois not always clear, which led to higher-level conversation about deprecations.
