Just as a matter of principle that you don't mix different kinds of information. It is the principle of "normalization" or "normal forms" in database theory. The hostname is one item of information, the domain name is another. You should be able to change and manage them independently of one another. If you always store the domain name as the host identity then you have made it very hard to separate those two pieces of information, and have made relative information absolute. It is also possible to record information that is incorrect and does not match information in DNS this way. Again. normalization says this is a bad idea.
