You're not the first person to suggest this and at this point you won't be the last. I'll just repeat what others have said every other time this has been brought up:

"It isn't fun spamming more buttons to be equal to someone who only has access to a 2 button combo."

May or may not be paraphrasing. Then you open a new can of worms about people being rude to others because they don't have access to certain abilities etc something something. tl;dr There are flaws to your suggestion as "nice" as it sounds.
