Rich,
It could be so because at medal play noone wanted to see a round ruined on the first hole because it was dicey and prone to producing high scores.
Especially with the concurrent influence of TV where the ideal finish was a crescendo ending at a difficult 18th.
If the leader/s tripled the first, all the air would be out of the balloon.
If you don't think there was a shift in emphasis from match to medal play in the last 60 years when TV was coming into it's own, you're out of touch with reality.
Mark,

I don't think that the issue is having a round "ruined," but rather the issue of placing pressure on the very good golfer from the gitgo. In the anecdote I used (Castle Stuart), it was obvious that the very good player I was playing with could drive the green, but also hit it into the gunge on the left (or the sea on the right --unlikely for a very good player). As the anecdote said, he did both. But we were just playing for fun. If it had been tournament conditions from those tees I have no doubt that he would have hit a long iron or rescue club to the prefered distance for his scoring wedge and gotten either a par or birdie. That he got a par on the day through drive, reload, drive, putt show that there is a chance for the bold and good player to score 2 on the hole. Same, I'm sure for #1 at NGLA.
As a corrollary, I was up in Dornoch this year concurrent with the Scottish Amateur match play championship and watched many players (95% scratch and below) tee off from the 1st (very driveable hole for good players (330)), virtualy all of whom took a rescue club or iron, bascially to take the 5 out of play rather than go for the 2 or tap-in 3. This was proper risk management (even if boring) which proves that your theory that medal play is to blame for all the ills in golf does not hold water.
