But by definition, the people typing the names of the dependencies into
a 'setup.py' for such a plugin *are* Python programmers, and could be
expected to know about case sensitivity.

I don't think Jim was areguing that human-centric *search* should punish
misspellings, but rather that encouraging such sloppiness in other
packages is a misfeature, especially if supporting it induces a tax on
*all* users of automated dependency resolution.
