I agree there would be no observable performance improvements.
But I never made any claims about performance; my motivation for this
trivial patch was more like just "code tidy" or "refactor", so
applying performance as the only worthiness criteria for a "code tidy"
patch seemed like a misrepresentation here.
Of course you can judge the patch is still not worthwhile for other
reasons. So be it.
