Sure, that should clearly still be the end goal... The idea would be to
keep deprecated functions in the client lib until we consider those
releases that need them truly dead. Not saying it's the best option
ever, was just curious why it was not listed in the proposed options :)

This is not about changing "stable requirements": havana servers would
still depend on "python-keystoneclient" like they always did. If you use
an old version of that you are covered, and if you use a new version of
that, *that* would pull keystonemiddleware as a new requirement. So this
is about temporarily changing future keystoneclient requirements to
avoid double maintenance of code while preserving compatibility.
