All legacy CLI commands should work as expected with a few
minor exceptions:
- no upload animation
- no interactive pagination
- help/usage output has changed
Deprecated options are indicated as such in their usage info. Deprecated
commands have descriptions that label them as such.

Rather than depend on magic, I would prefer that we explicitly call
two different request methods: json_request and raw_request. The
former will encode/decode request bodies to and from JSON, while
the latter will not.
