annotating code rather than data

Slightly off-topic, but I wonder why this approach (code annotations)
has proved more effective / successful, with atomics, than annotating
data. Usually it's recommended to put emphasis on data structure design
(with invariants etc), and then the code "writes itself". (I feel like
there's a famous quote to insert here, but I can't remember it.)

So I'm not questioning that annotating code is superior in this case, I
just wonder why it diverges from the usual guideline.
