Indeed, choosing a country of descent can give a player the opportunity to help their chosen country compete in the World Cup. This also helps maximize their potential. However, this can also be a mistake, such as several naturalized Indonesian national team players who lack playing time in the main squad. They have sacrificed their citizenship for Indonesia, but cannot make the starting eleven. How do these players feel? There will be disappointment for sure. This means it's not just about trends, but also the player's readiness to choose their country as their new citizenship; they must accept the risks too.
Do they need to give up their original citizenship in order to become Indonesian citizens? Do Indonesia allow dual citizenship? Here in India, dual citizenship is not permitted and therefore those who want to naturalize need to give up their original passport. That said, moving from any European country (say Netherlands) to Indonesia doesn't automatically mean a guaranteed place in the playing XI. If the player is good, then he will gain a place in the XI. If not, he need to work hard and try to gain entry.
