No flips for you!
Like @Bedrockgames said D&D, and in particularly 5e, has made attempts to appeal to a wider market. It had to.
They have Rule 0, Personality Characteristics, the Inspiration Mechanic, The Role of Dice which discusses Say Yes/Not and Roll the Dice, Plot Points (which caters for player authoring), Success at a Cost, Degrees of Failure, and even Multiple Checks (sadly not going to far as to fully adopt the 4e SC, but its kinda there).
I think they have done a stellar job and the shift has already happened.

All of those are, however, gated by the GM, not the players. The locus of authority is still, with all of that, firmly with the GM. Well, plot points, aren't, but that's it. 5e is still very, very firmly DM-centered.
