Jazz pianists have been doing this for decades, starting with Herbie Hancock , Keith Jarrett, and Chick Corea (and probably Abdullah Ibrahim). For me the sound is like the tine of a kalimba: a short but clearly-pitched thump.
For local jazz pianists, I've loaned one of my stringing dampers (a strut from an upright plate covered with used back-rail felt). The weight of the cast-iron by itself is not enough to match the damping of individual finger-tip pressure, so the pianist still has to reach into the string plane for a final 20% (?) of pressure. But it also gets you a full octave (depending on the length of the bar).
As far as the contraption shown here, a "better mouse-trap" could be devised.

and dies if one be gone
Strange that a harp of a thousand strings
should keep in tune so long."
