I'm not sure if this wasn't already mentioned, but HPC practicioners
can already use --tune.  Maybe HPC practicioners can have --without-
hardening.  However, in the computing I do that needs to be high
performance (*), it seems that the expensive computations are matrix
multiplications, eigenvector decompositions and the like.  I wouldn't
expect those kind of things to be hindered by hardening.

(*) In my case, this is not about supercomputers or computer clusters,
but about having software run fast enough on the hardware that is
available.  In some situations, that's a fancy supercomputer, but often
a simple laptop can do ... if the software is sufficiently optimised.
