I have two decks I consider rather minimalistic: David's Tarot and I-Ching Holitzka
And they are REALLY good for readings. I never had problems running out of insights but then again, I don't read so much every day that could prove that they are too restrictive... What bothers me are not the style of decks. Variety should always be encouraged,imo. What bothers me more is the word TREND...
I use the I-Ching Holtizka, which I love, in combination with the WU. They pair beautifully.
In terms of minimalist or not, how could one possibly reify mood, inclination, emotional state...these are often what determine whether I want to read with a lot of detail or whether I want minimal and by their very nature are as mutable as breath. I use both types of decks with equal engagement.
