It can be useful, but I’d treat it as a controlled risk rather than a trick.
If the opposition have dropped very deep and your goalkeeper is comfortable receiving outside the box, moving them higher can help you recycle possession and keep the team connected.
The key is protection if the ball is lost.
Your centre-backs need to know how wide they can split, and the goalkeeper must recognise when the opponent still has a player capable of threatening the empty goal quickly.
I would only use it with a keeper who is technically and tactically comfortable.
Practise it before you need it.
At U16, the idea can be excellent learning because it shows the goalkeeper as part of the team’s possession structure.
But game state does not remove common sense.
Higher positioning should improve your control of the ball, not turn every turnover into a shot from halfway.
