For the main screen, I think we can have a single resource with scopes
representing each link on the menu. Then we can ask for "give me
permissions for Main Page" and have only the set of permissions required to
load the main page.
Another thing I was holding to implement is a way to configure which
resources can be obtained as a result of a general entitlement request
(without any specific resource and scope). So you can have more control
over the initial load of permissions and use incremental authorization for
the rest on a per resource basis.

Yeah, considering that use case a tree would also suffer from
usability/performance issues. On the other hand, a specific tab on each
resource looks more "bullet proof" but bring usability issues.
I think AuthZ UI can handle this as well depending on how we decide to do
things. For instance, suppose we are creating a role. At that point we also
create a "Role A Permission" with a default policy (probably granting
things to superuser only). Later, if you want to change the
permission/policies for this role you can go to AuthZ UIs and perform a
partial search on the permission list for "Role A", which will bring you
the "Role A Permission".
Something to try before implementing more things, I think ...
