Indeed.  I am worried by the proliferation of command-line
optimization flags that have obscure meanings that are difficult to
understand by anyone unfamiliar with a particular computer
architecture.  This sort of tweakage might be mostly used by people
doing benchmarking.

When should this flag *not* be used?  To make it more useful, is it
possible to make any of this the default?  Can a system where it is
advantageous be autodetected?
