I wonder if you mean the same thing by "headless seedlings": one variety we grew in the commercial greenhouse had only a 48% germination rate, and two of those seedlings were "bald," that is, the seed coat was gone, the tip had not been munched, but there were no seed leaves.
It took 8 of us to pot up about 1100 seedlings in less than 4 hours. Only one person pointed out a helmet head, which was easily dislodged because the plants were so wet. They started out on a heat mat and then were at the mercy of the greenhouse's overhead misters.
At home, I get lots of helmet heads. I tried covering the seeds with vermiculite instead of potting mix and still got lots.
