Keyboard Toolbar/Button SwiftUI

I think it's is really unfortunate that you can't set the first responder in SwiftUI, as an apple engineer stated in this forum.

Will it be possible to add an own toolbar, custom buttons or similar above the keyboard?
Will it be possible to automatically shrink the current view when an keyboard enters the display (like in a VStack).
I really wish be could do more with the keyboard, since it is an essential element of the user experience.
