Naturalized players have been a long debate and it has been used by PSS for a long time and strangely it has not had a big impact on the development of the Indonesian national team but PSSI is still continuing their way of recruiting national team players, it would be better if PSSI started coaching from the bottom right only looking for naturalized players, as long as PSSI doesn't change its ways then Indonesian football will develop in a less encouraging direction, but I doubt there will be any changes in the near future because the focus should be on getting results instantly, while coaching from the bottom takes years or even decades before finally enjoying the results of seeing Indonesian football growing rapidly.
Of course this can only be proven when the tournament is underway, the junior team's strength map is a bit different from the seniors so maybe the Indonesian team here has a good chance to win a match or even qualify from the group phase, and the mentality of the Indonesian junior players will be tested in this tournament Are they strong enough to take the pressure during the match?
