One question is: should this be set to "Yes it is for kids"? My
understanding is Enabling that prevents Comments being enabled, but I'm not
sure if there is any other benefit. But yes, this is NOT a documentary
and is intended more for a middle/high school audience.
You probably shouldn't enable "Made for kids" as it will disable lots of
other features, including saving the video to a playlist including Watch
Later. So it's essentially all drawbacks and no benefits.
