That plus the idea around tying it to a custodial "parent" account so that a parent can keep tabs on who they are following vastly improves the current situation.
AnecData alert : We tried Youtube kids in 2019 for about a day (for my then 4 year old son). We were so shocked to see suggestive content and other crazy stuff from "verified" and reputed (100k+ followers) that we uninstalled the app then and there. There's no worse insecurity than a false sense of security
And yes, I've heard all the stories about YT Kids, and even took a brief look. We're staying away from it. Some research + youtube-dl is our way of choice for sourcing songs for our kid to listen to.
