Yes, only <shared>true is used for now.

I don't think so. If dependency is built with <shared>true, you link to
it dynamically. In general, you cannot change your mind after dll is created,
and link it statically.

I view the current "shared" as saying: "use shared linking whenever possible".
Of course, if you want to use shared linking for exe, you'd have to use
shared linking for dependencies that are libraries. So, <shared> is 
propagated. If you introduce another feature, then I cannot say
<shared>true on a single exe and have all dependency libs built as shared too.
