Completely agree. :)

Yup, agree. Also keep in mind that some operations may be duplicates
across services, just with a different context. For example,
in a deployment where you use glance backed by swift for nova,
os-compute describe image <id> may be the same as os-image describe
<id> or os-object describe <id> (swift), but the os-compute is in
the context of instances so it could have more metadata. This will
mirror the dependency tree we see between services (especially as
they are split out).
We want to make sure there are tools so services can stand alone as
needed (for example, os-image if you run glance standalone). Services
that combine other services (like nova) should aggregate these into
context-specific commands so you don't *need* to use the underlying
service tools for most things. This allows you to control nova use
one tool. :)
