Don`t really agree with this, my Myford ML7 has plenty of "feel" with the screw feed tailstock -I`m pretty used to it after 45 rears and have only broken a couple of (small) centre drills in all that time.
I sometimes use a small centre drill for starting 3.8 mm holes in front panels - gives more accurate results than going straight in with the finished size.
