I've seen those cameras used in tennis, and cricket, and indeed any additional perspective is good to have. But I still think it doesn't beat the POV of actually feeling you are following them around on the ice as a skater yourself.
I used to watch a lot of tennis and always prefer the court-level films posted by spectators on YouTube to professional coverage because it gives a much better sense of how fast they are moving, how fast the ball is coming.
The same goes for film of people doing rollerblading "flow" videos which are often filmed by people on scooters or bikes, following, or by the skater themselves with a selfie stick.
