What do you propose one should do when the current system to which Atom output is to be added do not record such updates but only records the date when the bytes changed?
The modification dates in my current RSS feed are based on the HTTP Last-Modified value returned by Apache.
The current wording of date:updated has exactly the same issue. It's not relevant to this pace. You do have several options
a) Use Last-Modified, asserting all changes are "significant"
b) Use the same date as atom:published, asserting no changes are "significant"
c) Use Last-Modified, since it's SHOULD NOT and not MUST NOT, so if you've consider the interop issues it's fine.
(b) is my favourite because it's by far the most compatible.
