code. That makes it easy to refactor code as a plugin or move in a 
plugin that was found to be really useful.

Given that, your proposal would mean that different parts of clang would 
use a COM like interface. Having seen a codebase that does something 
similar, I would say it is not worth it. It complicates the code and 
actually make code harder to factor as it moves compile time checks to
