Seems like you would absolutely need it in core files, otherwise the debugger won't know what it is when performing a post-mortem.

If we add a ptrace accessor a'la Linux, then it fits nicely into the existing model we have for ELF core files:

 * We also use ptrace(2) request numbers (the ones that exist in
 * machine-dependent space) to identify register info notes.  The
 * info in such notes is in the same format that ptrace(2) would
 * export that information.
