Stockfish likes the stacked 4 pawns.
Doubled pawns are OK, like e.g. in the Ruy Lopez. Tripled pawns are OK, there are some Spassky-Korchnoi match games on this theme. Even here you were winning at the end if you had not lost on time, but black defended badly. Generally speaking 2 connected passed pawns on the 6th rank are usually worth a rook.
Doubled pawns can be okay. Doubled centre pawns can exert a lot of control and can be pushed later on to great effect. Doubled a- or h-pawns are probably a disaster. Quaded pawns are just funny!
Four passed pawns! What's not to like?

Awesome. A 10 for pawn designs in your game.
