I think from users point of view it would be helpful to have only one
clearly documented glossary and way to do things.
At the moment, at least for the Python documentation, is not very clear
what's the difference between feather and ipc.new_file
Deprecating the Feather terminology would surely solve this problem, but
even if we don't end up deprecating it I think we should make more clear
what users are expected to rely on as otherwise there is the risk is of
building a product that competes with itself and ends up creating confusion
in users.
