Yes, I also think it the reference counting should be used only for
heavier objects, e.g. Module, Preprocessor,
Linker etc., of which you only have one or just a few.
If you use clang/llvm only as a blackbox library without looking into
the internals (like AST) then
refcounted objects would be cool.
