Agreed ... but the decisions embodied in the code-as-it-stands are
even more arbitrary, being no doubt mostly based on "which function
did you copy to start from" not on any thought about performance.

Now that somebody's made an effort to identify which places are
potentially performance-critical, I don't see why we wouldn't use
the fruits of their labor.  Yes, somebody else might draw the line
differently, but drawing a line at all seems like a step forward
to me.
