The problem is that it's very hard to convey subtlety & uncertainty. Sometimes the truth is "we may go in one of these 3 ways so we have to cover our bases to be able to go in either once we do know" but people (especially programmers) want to hear "we will do exactly x and it will not change in the short term".
