And if no namespace is provided (

key2

is absent,

key1

is

bar

), then the project name is the namespace.

Yep - that's exactly right. In most examples we've removed that argument now, so in general you shouldn't have to think about this at all (unless you are building a library). https://github.com/pulumi/pulumi/issues/2166 may also further simplify this.
