Any such optimization would have to be at the cost of more complex code.
So there's always a trade-off between optimizing and keeping
code maintainable.  In this specific case, you're talking about an
optimization that is only useful in 1 particular case, whereas the usual
rule is "optimize only the common case".
Of course, maybe there's a way to solve your problem without making the code
less maintainable, but it seems you're the only one with enough motivation
to do it, so if you provide a patch for it, we may consider it for
inclusion, but otherwise I think the problem will stay unsolved.
