Because probes are introspectable, it's actually better to remove them
than to change their semantics -- the tools can adapt more easily to
this.  Of course it's good to have a transition period, or at least some
sort of warning.

As I recall we had some thoughts about ABI compatibility when adding the
probes; namely that it is ok to add arguments to the end, but not ok to
remove arguments or to change the meaning of existing arguments.
