And, well, I am sympathetic to the argument that Google shouldn't do things the wrong way. But you really have no leverage to make them. Google offers the ability to use Gmail for e-mail sent to your domain, that's Google Apps For Business (or I guess Google Apps For Work). If that's unacceptable, you either have to deal with Google not caring about your needs (unless you're paying them, you're not the customer anyway) or do without Google.
