I don't disagree, this is not meant to be a challenge so much as coming it from another angle/context that I'm curious if others have had this experience: Sometimes I have found that without broad long-term phase due-date, features keep getting added forever. The due date can be helpful with product owner type people to get them to actually prioritize, decide which features are actually essential. Without a due date "oh, every feature is necessary", but if you say "OK, we had a deadline and we don't have X, Y, and Z done -- do we need to postpone it?" "Oh, no, we can totally go live without Y and Z" -- and then once you go live, they learn more about what the users really need and it turns out you never need Y and Z -- that without a deadline they were insisting you couldn't possibly go live without.
