It avoids having to deal with backward compatibility cruft?

It's a pain for client code, but I suspect that for the long-term quality of
the code base it's a useful decision.

You can do that without presenting a self-rewriting web-site as your

I have nothing against fixing LLVM. I have something against being unable to do
any kind of regression testing because I need to massively change the test along
with the library. That can't really help quality.
