> Ideally we should remove all v1 dependencies, explicitly (here) and
> implicitly.
> maybe for the env vars, we should consider adding our own env var provider
> which could go into branch-3.3 *now* as a single patch, which can then be
> cherrypicked by anyone who wants it in older releases; the v2 version will
> work with the new api
