The problem with the standard rule, equivalent to "taking 20" in 3E, is that it shuts down team play. Whoever has the highest skill modifier steps up and does the task. Either that PC succeeds, or that PC fails, but no one else can contribute in any way. If the person with a +5 modifier fails, the person with +4 is guaranteed to fail. Helping just grants advantage, and advantage means nothing if you're already getting 20 on the die.
I like Sacrosanct's idea. I do think it needs a little fleshing out, though. If you've accumulated a hefty penalty, can you still help someone else with the task? Is the penalty permanent or does it reset? If it resets, when/how?
