I agree. Plus, I think people know the value of this and that people purchase multiple cast recordings of a show. After Company was revived on Broadway in the 90's, the production recreated in London, and both versions were recorded and both released in the States (and I'm guessing both released in Great Britain, too). There's an audience for this.
