I done this and it feels like I kinda cheated the game by gaining lives without any effort whatsoever, before having the three crowns (1110 lives) I had 80 lives which I was happy with and that made me go around collect coins to attain more lives.
This trick is also usable on other Mario games too, not just Mario 3D World but I wish they would get rid off it because as I've said it, it takes away the point of putting effort into obtaining the lives.
Maybe I should send an email to Nintendo and see what their customer service says about it.
Edit: I meant to write glitch/trick and "patch" was for fix/patch. I messed up.
