I noticed a CS'r had put grease on his lens mount when I accidentally took his lens, thinking it was a demo set. That was during an equipment molestation session some time back.
Mechanically speaking, spreading a thin layer of grease will reduce friction when mounting/dismounting the lens, but does it actually helps?
