Simple,

1) Drills don't make straight or accurate holes, and

2) Reamers follow the existing hole.

Long story short....Not an issue provided the center drill has an
unobstructed path to the flat. My only concern was how best to present the
flat to the center drill. Don't see any reason for using an end mill to
clear a path if a normal drill will do, and so far no one has suggested that
it won't.
