[Python-Dev] PEP 594: Removing dead batteries from the standard library


Quick note on the pip discussion: if the likely remaining users of a module
slated for deprecation are professionals maintaining some legacy code, pip
is a fine solution. OTOH if the likely users are beginners, maybe pip is
not great.

In general I think it's fine to err on the side of caution -- as someone
already said, we're only removing *dead* batteries, not *leaky* ones. If
there's too much pushback for a particular module, maybe it's not dead yet.
We can make another list in a few years.
