Blind/Semi-blind tee shots have become taboo because everyone (or at least 95% of golfers) love the framing style.
I believe all is not lost. Quite a few "Joe Publics" I organise events for think that the courses with a few blind / semi blind shots are awesome, tee shots and approach shots alike. None of them like it as an overall theme (because the framing point is quite true). But as a 2-4 times per round thing, it seems to add to their enjoyment and rating of the course.
Here near Melbourne, I'm getting a lot of love from the regular non-archie inclined golfer for the wild and woolly courses that look like converted paddocks, refuse to be typical modern clones, and whose grass colours reflect the seasons. And being that this group play together a lot in a series that is as competitive as any and yet played entirely in great spirit and among friends, "unfair" predicament tend to bring more gasps of awe and learning than they do scowls of discontent.
Now to the inverted bunker. The "unkempt heap" or inverted bunker has got to be a viable element at quite a variety of sites. Quite a few old threads have raised points in passing that bunkers often don't look in sync with the plot of land the course is on. This is obviously due to the fact that many open spaces of land don't of course have any precedent of cavernous holes filled with sand dotted around. I guess thats why good bunkering is so treasured. Because it doesn't smack you in the face with suspicion, since the archie makes it look more like it should be there (and it helps that they appear on a golf course, a perfectly acceptable place to find sandy holes in the ground in the name of bunkering).
The unkempt heap is a feature that in some form or another, would surely look quite fitting and natural in almost any variety of site. And what's more, it can provide another architectural element (like a raised bunker lip) of blocking or semi-blocking a player's view of a shot from a poor position off the tee, adding more scope to it's value than merely to those who are directly on it. It also therefore provides an element of "blindness", without being arbitrary (because other players in the group in better position may have a better look) on a course where auto-blindness is not well received, and without the same length of walk / ride for the player to go and see what actually is ahead.
