I will take the other side of this debate. What if something happened during your touchdown ie. bounces, lack of traction, failed brakes, the list could go on and on? Not putting yourslef in the position of having to worry about if the plane in front of you is going to be out of your way is the best position to be in.
I instructed at a very busy uncontrolled, 3800' airfield and we didn't even allow position and hold procedures unless we were at a controlled field. Too many unknowns like a/c without radioes, etc.
I agree with what's been stated above, it's all about your comfort factor and the level of risk you want to take. However, imposing this kind of risk taking on a fresh, impressionable mind such as a private or even instrument student can and usually does lead to many other bad habits down the road. I have always and will always err on the side of caution.
Keep in mind, too, that the publications cited above are ATC books, not your standard FAA reading material for the various pilot certs and ratings. They are good extra reading, but not every pilot will have read these manuals. The AIM is the "bible" for pilots. Admittedly, I don't have it in front of me and can't quote it, but check it out and see what it says about multiple a/c on the same runway.
