Another possibility may be to provide a backward-compatibility module
that maps new tracepoints to old ones.  On demand, it could attach to
the new tracepoints, and export those callbacks as clones of the old
pseudo-ABI: same old names & parameters.  If the new ones supply a
superset of events & data, this is technically possible.
