That wouldn't help people building Ruby from upstream.

Any tool generating tabular output like this should add new fields at
the end (or show them only if requested), since there are bound to be
scripts that parse the output like this.  So I think Fedora's change to
readelf was reasonable, but should have been pushed upstream as soon as
possible.

Now everyone is going to have to deal with both formats.
