Impossible to use framework "AppleScriptKit"?

I know this is deprecated/obsolete and never worked properly and is probably just a dumb idea to begin with…but I’m trying to see if there’s a way to use the old AppleScript Studio (not AppleScriptObjC) features in any way on current systems?

Obviously, the Xcode templates are long gone. (Anyone have them saved somewhere?)

I’ve tried use framework "AppleScriptKit" which doesn’t cause an error, but doesn’t help anything. The framework itself does exist under /System/Library/Frameworks and I can browse the terminology dictionary. Halp?

The framework is there so old apps have a chance of running, but it’s pretty slim – too much stuff has changed.
