Are there ever scenarios where more pawn islands are preferred? In chess, it is usually advisable to have fewer pawn islands than your opponent. However, while I was watching a youtube video by someone called agadmator chess, he mentioned that multiple pawn islands do have their benefits and I'm trying to understand what kind of benefits or scenarios where multiple pawn islands are an advantageous factor.
Such scenarios arise occasionally in the late endgame.  For example, this position is a win for white (LiChess):

[fen "1k6/8/8/7p/P2P2pK/8/8/8 w - - 0 1"]


while a similar position (where white has fewer pawn islands) is a draw (LiChess):

[fen "1k6/8/8/7p/PP4pK/8/8/8 w - - 0 1"]


In the first case, if black's king captures a pawn, the other white pawn promotes (although white needs to play precisely).  In the second case, black's king can stop both from promoting because they're closer together, i.e., because of there being one pawn island.
