I'm no fan of repeating that comment over and over again. Let's just drop it,
people who are curious will learn by looking at the header of that file.

Done.

That should really be a typedef inside ConfigurationPolicyProvider, no?

Done. As you wish.

Can we name that similar to DecodePolicyValueTree? It does the same thing, just
on a different data structure.

Done.
