Must have features to be included in upcoming iPadOS

I have been advising my kids to use iPad for their online classes and for other activities like kids' games, videos etc. However, while my kid was using iPad, I feel there should have been some control options available to control kids' activities. Following are few options that should have been available. 

• Kids only mode: With single user mode it is difficult to restrict kids from using other unwanted applications and to restrict them from using YouTube application. The kids wanted to use YouTube to watch kids' videos, but the videos are interrupted with unwanted advertisements and incompetence videos.   
• Brightness control: My kids learned how to increase brightness and with their smartness, they increase brightness as they wish. iPad does not have control to lock brightness level and option to set specific brightness level for kids. 
• Unrated advertisements in applications: It can insert ads in application to earn revenue for developers, however most of those times kids were shown unrated advertisements and with paid applications. There is no option to restrict paid application advertisements in applications and to block unrated advertisements across iPadOS. 

Hope Apple addresses above concerns with kids only user mode and options to control screen brightness. For more such analysis, please feel free to check out G R Team Sites.
