And the reasons he gives are:

	1. In case developers of Atom clients are stupid; and
	2. In case your permalinks change.

#1 is an exercise in making things foolproof, which is not even worth
bothering trying, as those fools can be so ingenious. As for #2, it's
fixing the wrong problem: if changing permalinks causes the Atom ID to
change, then you should fix your permalinks which are not supposed to
change!
