I am mostly interested in `PrintCompilation` myself, so that would be an acceptable compromise.

However, I do believe that `PrintInlining` along with `TraceTypeProfile` are very useful to figure out performance anomalies in the field. Those really should not be diagnostic, and UL should really be "info" for them :) But we can have that discussion at some point later.
