For what it's worth mate I think you're spot on about developing players. Not sure what leagues you do but the ones I'm reffing are full of kids destined for sunday or saturday leagues at best. If both teams would benefit from an example then go for it!
Had an adult women's game sunday, one team full of 16/17 year olds who just came up. In every sense they are still children, so when one does a borderline foul throw, I lose nothing by saying as we run back "don't worry about it but just make sure it starts fully behind your head next time" with a smile.
I wouldn't do it at an academy game but for your average park game there's no problem. Good for you for seeing the benefit of it at such a young age, I'd be proud.
