Thanks for all the info. As I suspected, there is no single right answer. I asked the question because there was an incident recently at my airline where a new FO dropped a wing farther than the captain liked. Blood pressure was raised, emails were written. The senior captain who was ranting to me about it informed me that the wing should never be dropped on a large jet. Got me wondering where he got that idea, and what theories existed around the industry. Our manual calls for using bank as necessary to prevent drift, with the caveat that wing strike occurs at 8 degrees. I've seen several captains use zero aileron on T/O roll and landing roll-out in crosswinds, and it always feels very wiggly and uncomfortable. A large jet doesn't actually slide sideways on a dry runway, but it feels like it really wants to.
