Of course, but the benefit is to fix performance bugs in

I really don't know how. Suggestions welcome.
I'd put the onus on the proponents of the Change, who made predictions
like "I'm confident that over the course of the next year, we'll recover
performance that was lost by FORTIFY_SOURCE=3 and frame pointers" and
"The optimizations enabled by profiling can be much larger than 3-10%.",
and that's just in the last few days.
There needs to be substance behind such predictions if they are going
to be used as justification for slowing things down in the mean time.
