PC's are designed so that the CPU is idle most of the time, irrespective
of the power of the CPU, that has nothing to do with wether or not
binaries should be as efficient as possible.
If we do provide the ability for users to compile their own CPU optimised
binaries, then how can it be a bad thing ?
Would it be bad if their binaries are only marginally more efficient ?
The only "cost" involved is that it would require us to be more organised.
