Is it permitted to perform full prostration (pishut yadayim v'raglayim — spreading hands and feet face down) during Nefilat Apayim?

Synopsis

The Rema rules (following Hagahot Ashri and Rivash) that full prostration with face, hands, and feet on the floor is prohibited for everyone, even if there is no stone floor. Leaning to the side is permitted as long as there is no stone floor. For Yom Kippur prostration, spreading grass as an interposition is the accepted practice.
