Correct. Which makes me think of various c++ template libraries MS has shipped alongside SDKs (ATL, WRL). Actually the same reasoning could be said to apply to

Correct. Which makes me think of various c++ template libraries MS has shipped alongside SDKs (ATL, WRL). Actually the same reasoning could be said to apply to STL. Or, relatedly, somehow it's possible to link statically to CRT. It's interesting with these cases, because something can seem perfectly reasonable behavior in the mind of a developer (an app using platform headers or standard library) but you can wind up with a different answer trying to figure out for what if anything enables that behavior in a legal context.
