I guess it comes down to preference. In terms of the core use case, we
really just talking about the mechanism to obtain a reference to the
service endpoint. In dynamic systems where services can be brought
up/down or upgraded on the fly, exposing a collection of available
services makes it easy to iterate over the provided services, making
metadata queries etc as required to discover what's available, what's
currently running, generate on the fly doco, and provide flexibility
with decisions around managing dynamic systems etc. I suppose we don't
need that sort of thing right now for Launchpad, but it's just as easy
to type:
lp.services['sharing']
as it is
lp.sharingService
And option 1 above is analogous conceptually (at least to me) to
lp.load('+services/sharing') which is also supported.
