I think it's still interesting to be able to run plugin actions instead of CodeGen. It's not certain yet, but we're (the static analyzer team) looking at plans to extract the analyzer and possibly the various Objective-C rewriters out of the main clang binary (or at least make them optionally built), and we'd rather not distribute two copies of Basic, Lex, Parse, AST, Sema, etc. that these kinds of alternate ASTActions would need.

(This is still in very early stages; it's possible our final solution won't end up using the existing, admittedly-flawed plugin structure.)

I'll try to actually review your proposal fairly soon; this just caught my eye.
