Precisely.

Despite what the docstring says we have to deal with the existing
software on the field.  IIRC at the time after a number of bug reports
was deemed that minimizing incompatibilities and making the
native-compiler as much transparent as possible was priority.

One option would be to update the docstring and add a second function to
return the true value similarly to what we did with
`load-true-file-name'.

The other option is of course what you've suggested.

Thanks!

  Andrea
