In my experience "target dates" have a funny way of transforming themselves into deadlines over time.

It's the confusion of estimates and plans with commitments. "How long will this take?" "About a week" "Great, ship it Monday morning" "Wait, if it has to be Monday then let's spend 30 minutes figuring out what needs to be shipped and what can slip until a later update release" "No, you said a week".

Like most things, it depends on leadership beating the dead horse to constantly remind people of the difference.
