As to vinegar, I can't remember adding a wine I found really bretty to my crock, but don't think I would be afraid to. Generally my crock is a combination of dozens of wines, and so any overt brett would be diluted. I would guess the low pH of the vinegar would retard any further growth. But that is just speculation, and certainly Dr. Lipton would have a more informed opinion (I last had chemistry or biology in high school, my college science electives were Rocks for Jocks and a cool physics for non-majors session). I do avoid adding wines that I think are TCA- contaminated, but often add things that I didn't choose to drink.
Like Rahsaan, I often cook with wines that I probably wouldn't choose to drink. Not a beef in barolo or bouef bourguignon, where flavor of the wine is to the front, but if a red sauce needs a half-cup of wine, to deglaze some skin and veggies, etc I'm generally fine using the wine I opened and found lacking a day or two before. I think the "don't cook if you wouldn't drink" is a remnant of the days when a fair number of wines were really faulty.
