I agree with galehar's sentiments here. When playing in person, it's not unreasonable to make a vague plan for your deck and remember what's important within the five cards you don't see in your opening hand. When juggling multiple games that span several days or weeks here on BGA (as many of us do), it's not realistic, and players are going to end up taking notes or screenshots anyway to get around it.
I think a reasonable compromise would be a toggle-able option, so that live games or others who want to play with the fixed ruleset can keep players' decks hidden, but those who want the option to be able to "catch up" to their games' state have that choice as well.
