Maybe even just printing a bit of text after a successful "add" to
inform the user that the just-added project isn't part of any image and
what they might want to do to include it?

The packagegroup sounds good too. But if the user doesn't want it
included, they might be confused about how it magically appeared, and
have some trouble finding how to remove it.

I can't help think that there's no harm in an unused workspace (is
there?). Maybe the empty workspace from "create-workspace" should just
be created by default by the "oe-init-build-env" tool (or whatever a
given project is using).

If I were writing the documentation for this workflow, or giving a
presentation on it... I'm just trying to figure out how to justify the
extra, empty (but necessary) step of creating the environment before
using it. Maybe if someone tries to add a project before creating the
workspace, instead of erroring out, just run the create-workspace for
them with the defaults. If they're a power user who wants to put the
workspace somewhere specific then they're free to explicitly call
create-workspace on their own, otherwise it'll get called with the
defaults for them (or created automatically as part of the
oe-init-build-env).

To borrow the analogy from git: create-workspace is part of the pluming;
it's there if people what to call it explicitly, otherwise it gets
called implicitly with defaults?
