Not here to argue but I wouldn't leave a part out the door for a machine without skimming both sides so when the part is repositioned for the drilling, that the edge face is perfectly square to flat face and all the imperfections left from when the stock was rolled are eliminated. These things all take time to get right and hence the 24mm width too.
You can argue in this case that the bore and edge are in the same plane so the angle between the flat face and bore doesn't matter a fig but if there are holes going in the side and even if they are clearance holes, I'd still rather do it spot on for when it is repositioned.
I can't comment on your mates work, I'm sure he's a damn fine machinist but I've seen too many things end up on my desk after jobs by people who have ignored the small stuff and it results in spindles misaligned and tapers on edges. Hence I'll stick to my ways and even if the skimming, clamping and clocking takes extra time, I know what goes out the door is good. If something gets past me, I know it's my fault and replace a part immediately.
I must stress that this isn't a dig at you Jonathon, I have read a lot of your posts and have a lot of respect for you - you know your stuff. But this is how I operate unless a customer requests that cost is the major factor.
