Do you think it might be worth it to have a PolicyProvider class which contains
"all" this policy stuff (currently just DeviceManagementService and
DeviceManagementPolicyProvider), so that the profile has only one accessor for
all the policy stuff?

That is definitely worthwile. I created a new PolicyContext class that bundles
all the bits and has nice accessors.
