It's not really something most people realize until someone points out those issues to them and they think a moment and have it make perfect sense. But having done both through my prior ignorance and present enlightenment on the subject, it is a very observable problem once you understand what's going on. I've lost a 3/8" carbide ball endmill to tooling foam before on my work's CNC router, that was one heck of a wtf moment. Generally tooling has a great dislike for sudden stops and changes in direction, and that's why most CAM software has many features for trying to reduce them.
Machining is a game of tricks, the more you know the better you can be at it. I love teaching students all the tricks I have learned over the years and find the moment of realization in their faces as they think "Wow, why didn't I think of that? That's so simple. Now I feel stupid." I then make it a point to the student that there are plenty of people out there that can just as easily make me feel that way. It would take several lifetimes of hard work and mistakes to learn all there is to machining. I'd be happy to die with a 1/10th of what's out there! I would consider that a huge achievement.
I get oddly philosophical about making/building/machining...
