What does this fix? Even if the current logic is "complicated", it is
still a pretty simple functiion.

Applying clean ups for fun has the side-effect of making backporting
more difficult. And swapping implementation randomly has the side-effect
of potentially introducing regressions. The current code might be messy
but it is still field tested.

I'm sorry but I have to reject this patch.
