I see a problem with this approach when the speaker does not know the answer to the question:
Under Abs-E, binary questions (“yes”-or-”no”) are less obvious to answer. If your answer would ordinarily be “no”, you must instead reply as if the question was open-ended. For example, your reply to “will you be here tomorrow?” may be “yes”, or “I will be in the office tomorrow”, or “I will stay home tomorrow”. This forces you to speak with more information.
How do you respond when you don’t know what you will be doing tomorrow? This could be a case where you haven’t made up your mind yet (in which case “I will decide on that later” is a valid answer), or it could be because you genuinely don’t have the information and have no way to find it. “What will the closing price of Apple be at the end of the year?” is difficult to answer as far as I can tell, especially if the person asking the question thinks you should know the answer. “You will have to wait for the end of the year before you can know that” doesn’t convey the same information as “Short of stock manipulation, nobody can know the answer to that until the time comes.” The first one could mean that I know the answer but choose not to tell you, while the second one conveys the more reasonable claim that the question cannot be answered in advance.
So, I think this is an interesting thought experiment, but I suspect that the amount of time spent mentally rewording everything before you speak will outweigh any positive value.
You almost always have some information to concentrate your priors. Between mutually-helpful speakers, implicit with an answer to a question is that the answer gives all the information you have on the question that could benefit the questioner. E.g.
What will the closing price of Apple be at the end of the year?
“Almost certainly somewhere between $150 and $250.”
