This is a nice idea but the claim that it is "not very hard to do" is incorrect. For starters there's the confusion factor which may trigger some support requests. That's more work. Moreover it may result in some consternation among customers who actually do desire the traditional salutation. That's a different kind of difficult, going against your customer. Again, not saying it's wrong, just saying it's not easy. There's maybe even a point in there about programmer tendencies to underestimate the full impact of small code changes...
