Sorry for that, updated in the original comment!

Sure thing. And it's helpful to know that people are happy with the "status quo" (for good reasons, as you note below).

> On the other hand, when hacking on Clang, I often grab a `-cc1` invocation and append `-Eonly` to only run the preprocessor. If that resulted in an error and forced me to go through the whole command-line and remove `-c`, I'd be very frustrated.

That's a very interesting perspective. We don't hit this use-case just yet, because our feature list is still very limited. But we *are* heading in the similar direction (in terms of our workflows).
