Yes, even my wife noticed the M5 adagietto. She called me in to watch the skaters, and then surprised me when she noticed the cuts and patches they had to make.
I too was annoyed by the piano part, but I guess we have to take whatever the skaters need to do to make it fit into their routine. Perhaps, on the bright side, a few more people may have noticed the music, and may further investigate the beauty of Mahler's works.
