Having just watched "Context Is For Kings" earlier today, and finally seeing the Discovery for the first time, I've developed a theory about why the design of the saucer (reminiscent of the Vengeance in the ST:ID) is so unusual for a TOS-era Prime Timeline design;
Saru mentions about the ship, a Crossfield-class starship according to Memory Alpha, can run a multitude of scientific mission objectives at the same time, 300 or so. So, the ship design clearly has a scientific lean, perhaps akin to a laboratory in space. When her sister ship, the Glenn, is introduced, it shows that this class isn't unique to the Discovery (or presumably a namesake USS Crossfield) and is referred to as being brand new.
What if the negative-space saucer hull design is a safety measure? The bridge is in the center module. What is the outer rings of the saucer have jettisonable laboratory sections? Similar to a standard 'saucer sep' situation, especially given how dangerous the experimental 'organic propulsion' system is.
Also, given the fact the design is considerably smaller then most ships (barring the NX-class), it would seem it's designed to have a minimal crew compliment at risk from the experiments.
