But is it only reduced? Or has the scope grown but in a different direction?

Consider IE 8 + Silverlight on XP vs. IE 11 + EME  on Windows 8.1. In
both cases, the  Key System is Microsoft PlayReady. In the case of
Silverlight on XP, as far as I can tell, the PlayReady implementation
doesn't have particularly magic capabilities compared to more mundane
DLLs. It's just userland software. On Windows 8.1, however, the
PlayReady component that IE 11 uses in the EME context is baked into
the system.

Sure, it's scope reduction that the CLI runtime is gone. But is it
scope reduction that the CDM went from a userland DLL to something
baked into the operating system?
