Lord, I missed the fireworks.
I would remind that legend has it that the 1st at NGLA was driven in its early days, and it cost someone an inheritance!! At the 2013 Walker Cup, over the course of two days' play, I believe I saw one world-class amateur lay up; the rest banged at the green with three-metal or driver. Same goes for hole #2. That's the combination of equipment and fitness.
I had forgotten the notion of a drive-and-pitch hole. I think the reason is, we are not the best at half-shots. Think about your accuracy from 30 or 50 or 70 yards, verse your full gap wedge. My guess is that the in-between shots cause you grief, more so than the full swing. If not, you win the majority of bets you make!
I have no problem with Tom listing his best short par 4 holes as evidence of an understanding of the genre. If I were at a teaching conference and failed to mention the tasks I utilize in class, bad move. Same goes for coaching techniques for high school golfers; they define my reason for being. Citing other architects' work is one thing, but establishing one's own facility with a skill elevates that one to a higher level.
There's no restricting a hole. The dispersion of shots based on skill, as has been mentioned herein, compels the expert golfer to play her/his ball more accurately, with greater consistency, than the weaker player. Therefore, the driveable par four is less so for the weaker player, no matter the tee deck. Same goes for the drive-and-pitch par four.
