This default credential doesn't have an access token. Is it appropriate to say
that it "authorizes" the application?

Same question on the wording of "authorize" as the previous comment.

When used, this does have an access token under the covers, as all types
inheriting from Credential do, but in normal usage the developer should not need
to be aware that this is the case under the covers. So I think this is OK to
say.

I have deliberately left out the well-known-file and Google App Engine support
from this JavaDoc because when this first releases, the Cloud SDK and App Engine
SDK pieces to unblock this will not be ready. This can be amended once those
pieces are ready.

As above.

Rebased and change some doc comment casing.
