I think that would get us more questions.

With -O0 it's usually obvious that the compiler isn't even trying.
With -O1 it's doing some optimization, but not much. We'll still get the "why 
does gcc generate worse code than (X)" questions. In addition we'll get more 
"why can't I debug my program properly" questions due to artifacts introduced 
by optimization. -O1 gives reasonably debuggable code, but it's definitely 
not prefect.
