If you look in the supplement, there's plenty of newly-bolted routes at Ban-y-Gor in the lower grades. Maybe not the best routes, but they are there.
As for Tintern, I've never been myself so I don't know how seriously to take it, but that section in the guide has the (oft quoted) dire warning, "It is definitely
not the crag for the inexperienced. In fact this is not the crag for people of a nervous disposition, the accident-prone, the unlucky, the uninsured, those who are easily disheartened, or anyone with loved ones"
