Note that if you put policies into the same group, then its not possible to set
their values to unspecified independently. (In case of ADM/ADMX.) Each of them
will be specified or unspecified at the same time. It's okay if this is what you
want.

In this case, RendererSettings is essentially a switch between these two lists. 
If RendererSettings is 0, then the RenderInChromeFrame list is used for
exclusion, if it is 1, the RenderInHostList is the exclusion list.  So I think
that's what we want.
