I much prefer the approach taken in D (IIRC) as I think there are real cost savings with the simplicity of expressions being either true or false. My experience (anecdotal) has been that both developers and end-users make fewer mistakes and take less time figuring out what the result of a query will be or what it means when using 2VL.

The link below is primarily descriptive rather than argumentative, it is not about D but an existing language, and it describes what you already grasp, but in spite of those caveats, you might enjoy reading:
