I have pulled successfully starting with the bar over the middle of my feet and pulling straight up, never moving the shins forward and never touching my shins with the bar. It's worked pretty well for me over the years, although it's not my current style/form. Pavel discusses this in some book, and I think (if memory serves) he calls it a Russian form as opposed to what you described which he calls an American form.
Can't find several of my books right now so I can't check, but for those with the requisite flexibility and posterior chain strength, you don't need to do it as you've described above.
I really think it just takes experimentation. My own preference is that people be able to deadlift from midfoot and straight up. This gives a very strong pull, and one can later add a bit of forward shin angle to help with the start.
I'm not claiming to be the last word on this, and things like this are part of why I recommend people compete or at least go for a real 1RM a few times a year - you just learn things you don't learn otherwise about what works and doesn't work for you.
Meet video can be very instructive. I got pretty harshly criticized by a number of my colleagues in the StrongFirst leadership a few years ago after they watched a meet pull of mine - they were all people who'd competed at powerlifting or Olympic lifting. That conversation, at a cert where we were all teaching, began the thinking that's culminated in some recent form changes for me. It was all good natured, of course, but they made their point that I wasn't lifting the best way possible for me, and it caused me to change my training to enable me to get strong enough to then change my form in the way they suggested.
It was pretty funny - after a few beers, they were all just looking at me telling me I was going to end up in the hospital if I kept lifting like that. Competition is competition, and you do what you need to make the lift, but it really did also start the wheels turning. And all this happened because I had a cheering section at the meet who was kind enough to take a good video on their phone. And that all happened because I decided to go to a meet and do the absolute best I had on that day.
