Okay, I got one. When commentators criticise a spinner's trajectory, you'll hear things about them not looping it enough, not 'getting it above the batsman's eyeline' or similar. Warne did this a lot. I don't think it's really a thing for two reasons.
Firstly, spinners tend to bowl fairly upright actions, without as much torso bend as a fast bowler (though you do get the odd one who really tilts, especially wrist spinners). Unless the bowler is short and/or the batsman very tall, the ball is almost certainly being released from above eye level anyway.
Secondly, when bowled at the kind of speeds you usually see in international cricket, there is little to no upwards trajectory on the ball. I don't often get to see professional bowlers, but when I do I find it almost astounding how fast they bowl. And (as a cricket nerd) when there's a speed gun I take note of what the trajectory looks like. I've found that for there to be a noticeable upwards component to the naked eye, it has to be at or below 80 km/h or so. While sometimes bowlers are slower than this, usually they're significantly over. By the time the speed reaches the low 90s, from fairly side on it looks nearly flat to the naked eye.
While I get it as a piece of advice to budding bowlers to not simply fire the ball into the pitch (though some bowlers make that work), modern professional bowlers don't normally loop the ball and don't really 'get it above the eyeline' other than that's where they release it from.
