I can't speak to when you last looked at it, but the current state 
shipping in browsers is, as far as I know, no different from what 
browsers shipped initially for purposes of this discussion.

If you specify script-src and style-src and don't include 
'unsafe-inline', sure.

CSP allows the things you don't issue directives for.  If you don't 
issue any script-src directives (or default-src directives), then there 
won't be any limitations on scripts.
