I'm not too sure Slag, but I think bite-off par 4s with cape greens (even if it is a cape jutting out into sand, waste or a series of sand or green bunkers) is also a popular theme.
But, as you say, many golfers don't really think of the concept of the Redan theme- or never heard of it- when they are hitting to the front to back offset green, with the deeper bunker at 7 O'clock front left and over the kickplate back right at 2-3O'clock. (or the reverse on the Nader)
And, the theme is carried quite often to the approach shots of par 4s, as well. It might be more to do with basic strategy or default mindset of the designer than just conciously emmulating the Redan per se.
The usefullness of shaping the ball may be getting lost more to the ball designers de-emphasising the shapeability characteristics, I don't know for sure. But, that still leaves firm maintenance conditions of the ideal Redan to allow a well struck straightish shot to land a wee short and take the kickplate roll whether Redan or Nader.
The real futility is if the green is pudding...
