It is the amount of surface area that they are trying to increase without sacrificing weight. A larger surface area help dissipate more heat. Hence the holes in rotors, waves, ridges, slots etc. Like the heat sinks in electronic parts have all those fins.

Nope,
but you can cut yourself on a rotor. I've done that just changing a tire.
The rotors can get a wire edge from wear on the pads. easy enough to knock off with a stone or some sandpaper once every 5,000 miles or so.
I doubt any pros rotors ever get more than a few hundred miles on them.

How do you even put yourself in that position? With your knee so close to the hub in what has to be a very awkward position? I just can't picture it. And if the disc can cut, why can't the cluster and chainrings? Something not right here.

Protective covers for discs?
Give me a break.
The large chainring is far more damaging to flesh, far more exposed, and is a common cause of injury.
I am curious if anyone suggesting using disc covers is also suggesting using the same for chainrings. These things already exist in the form of so called “bash rings” (common on mtbs).
Some bash rings are very light, but if you simply incorporated them into the chainring itself, it would add very little wieght, and virtually elimate injuries from the chain ring teeth.
Does anyone suggest mandating bash rings?

I heard the bash ring idea was nixed because of a high incidence of people being gashed by bash guards.

But obviously you can put on a chain guard if you wish.
Waiting for the excuses as to why such a guard should not be used but a disc guard should ... 3 - 2 - 1
