As I wrote on mailing list:
```
I'd like to keep backwards compatibility. We don't know where this might
be used.
Also the catalog item ID isn't sufficient I don't think. Returning just
the catalog item ID means you lose any custom configuration on the location in
the blueprint (ie on top of the catalog item ID); I'm not sure it even works at
all if you use legacy "jclouds:aws-ec2" syntax; and you won't get any
added-after-deployed information. It isn't a problem in many cases but it is a
weaker API.
Could we add a new "locationsDetail" field which contains eg "{ [ id: <old
value>, catalogItemId: <what you want>, displayName: <optional>, ... ] }" and
we could add any further metadata we want?
I'd also be in favour of doing this for all entities, not just applications.
```
