Why does Android ignore multitouch on accidental touch?

Question

Android

Example: A child holds a tablet in one hand and touches the screen, and when he tries to touch the screen with the other hand, nothing happens.
Why didn't the developers make it so that the first touch is ignored, and the second touch activates the action? After all, it is easy to determine what the user wants. When the first touch is not informative and the hand just lies on the screen, and the second tap (not a slide) is an action.
I searched all over the internet and couldn't find anything like it. Help please, at least what query in Google to type?
I'm even ready to turn off multitouch, and so that each new touch turns off the previous ones.
What I know about the problem:
1. With the second touch, you can scroll, for example, in the menu - a useless action. The behavior is as if the second touch continues the first.
2. Android itself determines well which touch is the first, and which is the second, and so on. There are many applications where you can check this.
3. There is an application from Samsung that disables the touch on the edges of the phone, but this is also not what you need.
4. There are touchpads on laptops, where with one hand you move the mouse and without releasing it, you click with the other hand. Not all touchpads support this.
