Minimalism is a nice thing, but you can overdo it.
Which is when the "oversimplification" (more fitting would be "overreduction") of something results in an actual decline of ease-of-use.
This Dilbert comic comes to mind.
Here, the overreduction led to the removal of the symbol coding on each card. The brain is much faster to recognize symbols like spade, heart, diamond and club over their written-out names (the words must be read and made sense of where a symbol is immediately recognized by its shape), so this change makes the cards much harder to use. Same goes for the value labeling, which usually is just a single letter, which comes down to having the same properties as aforementioned symbols.
