Interesting!
I didn't use the term "cheapen" but I do have a strong sense that penalties are not football. The goalie is at a disadvantage.
Soccer culture is a bit different. I think the closest example is in North America how both teams in football get a chance in OT, it feels a bit more fair. Imagine if Messi hadn't scored in extra time and the game was decided by Mbappe's penalty.
A good keeper limits the disadvantage. Martinez did very well with penalties this tournament, as did Livakovic for Croatia. You study tendencies, you read the shooter, you can try to get in their head like Martinez does. That's what makes the save so exciting.
