I think the worry for some is that the development league is potentially being done away with and the 8 elite teams will be playing each other in a closed shop (the rationale is that we need the best against the best to produce better players). Our youth teams would presumably be playing amongst other clubs out-with the elite, so the standard may not be as good.
As you say, we still have attractive selling points to young players, so hopefully that can mitigate any drop in quality. We may not be able to give them the most competitive youth games, but there's a clear path to the first team if they're good enough.
