I disagree.
If for some reason the I-D refers to information in the (to be)
obsoleted information, then yes. But this is no different than any
other informational reference. However, if the I-D simply has:
Obsoletes: RFC X
and text:
This document obsoletes RFC X.
There is no need to have an informative reference and, in my
opinion, having a informative reference for just such is
distracting and ought to be avoided.

You are right if there's nothing else that needs to be said.
Frequently however, a revision of spec actually makes changes, in
which case I would expect a "changes since rfc xxxx" section, which
optimally should be precise in what changed (potentially including
references to specific sections in the original spec).
