If this is a rhetorical question implying that it would be best if
the existing trace() were rewritten to be built on top of trace2()
while building this series, especially before adding new callsites
that directly use trace2(), I may share that feeling.  I haven't
studied this new round deeply enough to see how realistic it would
be, though.
