> However, "performance" also includes compilation speed in the 'no optimisation, debug' case - that is also considered very important. So, perhaps, the short-term approach should be (as @dblaikie suggested) to include the bodies for -O >= 3?

I don't think so. I think "performance" refers to the runtime performance generally. I don't believe the normal users will be happy if modules will decrease the performance of their program in any means. So I think we should include the bodies by default.
