IMHO, a lot of stuff is not specified in the current APP spec, even

In fact, I'm beginning to think that the APP is just a basic prototype
of a protocol or a web api. In order to have a fully functional and
interoperable
protocol, you need to roll out your own based on the APP, like GData API.

So, everything outside of the spec will be depend on some inventions from
variety of implementations in the wild.

This is an important point. Personally, I am OK with where we are now: once you've got your collections set up and authorization infrastructure in place, the APP lets you do CRUD operations on them in a way that's pretty easy to implement. The APP doesn't touch a lot of system management & administration tasks, and I'm OK with that, because we don't have enough industry good-practice consensus on what's important and I think that if we tried to standardize it we'd have to invent it first, in advance of experience, and I don't want to go there.

However, I still do see a couple of missing pieces:
- There really should be a standard way to retrieve a list of available categories. - To the extent that we can provide some hints and support around authentication, that would be a plus, so that a dumb client that can do HTTPS+basic, *or* next year's best choice, has a chance of figuring out which the server wants and switching that in automatically.
