Yep. At 57yo, I can put my palms flat on the floor.

Last year, I bought my first all-new, complete road bike in 30 years. When they were doing the initial fit for me, I requested they slam the stem and trim the steerer tube. Understandably, they were very hesitant to do that for a new bike and a not-young rider. After demonstrating my spinal flexibility with the above maneuver, they proceeded with setting up the bike with the stem slammed, but insisted on leaving 10mm of spacers above the stem. I took care of that stack on my own, at home.
