but I can't stand in-course out-of-bounds
I'd have to check my decisions book, and cross-reference with the RofG, but I'm almost 100% positive that in-course OB isn't a properly allowable way to mark a course. Basically, you're not allowed to have OB within the course, but rather on the boundaries of the course.
I remember Fairfield having to change the way they marked their course after numerous Junior Golfers challenged the setup during the Junior Met one year. I don't remember the hole numbers (I wanna say back 9), but there was OB between an uphill dogleg left par 5, and then a downhill dogleg right par 4 with water in front of the green. The OB was nowhere near a boundary, and the reasoning they had it was that if players on either hole hit it into the OB, they wouldn't conflict play on the other hole. Worst reasoning ever. But I remember them removing the OB stakes after the 1st Round, and they certainly weren't there for the 2nd Round. The time frame was between 1995 and 1998.
