It's not a matter of "looks a bit more efficient".
it's taste, style, and repetition for various functions.

Some prefer that source code be "templatized" regardless
of the number of exit points that any particular use of a
specific function type.

Some of your patches are converting these templatized
functions to a different form for no added value.

These patches make the local source code inconsistent
and generally goes against the authors preferred style.
