I think this would be great, and if you want I can help you
with some of this work.

There are even some features Sun's ELF has that the GNU
tools might want to support at some point, such as the
data section compression bits which are primarily targetted
at fortran programs.

So it really can't hurt to add detection and reporting of
these ELF features to at least readelf.
