Yet another python failure: python-pathlib

Materially, it does not look very difficult. It is probably enough to replace
   from collections import Sequence
by
   from collections.abc import Sequence

Metaphysically, this is a package with its latest release in 2014 (!),
the vcs page has disappeared, but it has many dependencies:

Why do so many maintained projects depend on an unmaintained library?
