I think it came down to Adm. Adcock stating that since they already planned to build DN-sized hulls for the ships off the assembly line, they might as well go for a full sized prototype.
Ultimately, my sense has been that dreadnoughts are going the way of the dinosaur in the Honorverse, as they were always a way to save money while still building ships-of-the-wall that could at least give proper superdreadnoughts a serious fight. At the beginning of SVW, some 90% of the Havenite wall-of-battle was SDs while only 60% of Manticore's was SDs (the rest being DNs). At the beginning of AAC, there was a debate about building DN(P)s and it was deemed not worth the time and money to design one, work out any design flaws and problems, setup the necessary assembly lines and then start building. It was simpler to keep on building the SD(P) which they would need to build anyways. So for Manticore at least, DN-sized hulls are the ships of choice for CLACs while Haven seems to prefer SD-sized hulls for theirs.
Actually, they originally wanted to make the testbed CLAC's even smaller than DNs, but the analysis of how they should/would perform always called for a minimum of a DN in the production model. And Admiral Adcock, then head of BuWeaps sold the testing by saying "the best scale is 10 millimeters to the centimeter" or something about that. However with ship size creep, what used to be called a Battleship is now Battlecruiser size.
And the ship choices are also material to intended roles. Manticore always envisioned their CLAC's to be used offensively, so a smaller hull to balance speed against brood was viewed as necessary. Haven viewed their CLAC's as primarily defensive, so SD's not only bring more LACs to the fight, they're tougher to kill.
On top of that, we've seen two real 'doctrines' of CLAC, even before we really tore them apart on forums. We've got fleet battle carriers (like the original Minotaur) that would drop their brood, and then fire off MDM's from maximum range. And then you've got fleet defense carriers (like the Grayson Covingtons, or Haven's SDs) that focus more on just maximum LAC capacity and they stay the hell away from combat because one good salvo will kill them.
Offensively, you could get away with a size creep battleship, because they're going to be the size of small (old) Dreadnoughts, and make great deep raiding squadrons. Fast enough to run like hell if you get ambushed, but enough firepower anything less than waller squadrons will get torn apart.
Defensively, nothing less than an SD makes any sense, because you want as many LAC's as you can get to protect your real wallers. And the SD's will let you use either half the carriers for the same LACs off DNs, or twice the LACs for only using full squadrons.
