Byron,
This site gets an OD of such bunkers, but out in the real world courses with these bunkers are anomalies. Granted, it does seem to be moving to the Dept. of Redundancy Dept. in some cases, but what is one to do if the site loans itself to the style and the course would be different from others in that market?
The other factor is long term maintenance. Not all these bunkers will remain as is. All it takes is one unsympathetic superintendent a few months and these bunkers can revert to standard fare.
Funny, I had some Italian investors who knew little about golf come by and look at a project with ragged bunkers. They had never seen anything like it and used your specific term; "Unfinished". I tried to school with a presentation, pro's and cons about the bunkers, and as their property was remote, the parcel small, severe... in the mountains (only enough to yield 5,800 heaving yards), I thought this would fit, make the course visually distinct from others in the region, and help drive interest. No dice.
The "unfinished" bunkers.
A few sketches I'd made for the investors:
Same hole with grass faced bunkers as a comparison.
