I addressed that in my post. All warships should look very similar, all recon ships should look very similar, etc. in order for the original comment to have any relevance to the show.
It's all 100% aesthetics on the show. Any rhyme or reason is rationalized in afterwards in order to sell tech manuals and the like.
No, not really, you addressed part of it and your point is well taken. Romulan ships are easily identifiable as Romulan, etc to the informed viewer. Less so however to a complete newcomer who might arguably just see "spaceships", which is more in line with my comments about non experts viewing tanks and ships. We hardly qualify as uninformed when we view ST ships.
More crucially to the point, however, Starfleet ships don't to my mind actually follow all that closely to the classic connie layout to cause complaint with the Discovery. Neither the Defiant nor the NX are remotely as close to the classic layout as she is, nor do all that many people seem to view them as being aesthetically pleasing, at least in the Defiant's case.
That's at least two out of the the five canon hero ships that deviate pretty sharply already. The design lineage has been fluid at best and as the canon has progressed we've accepted ships far less in line with the connie model with far less complaint.
I'm not remotely convinced that vessels are designed based 100% on aesthetics without functional considerations,but even if we let that slide the fact still remains that we don't know much about Fullers vision for the show, nor what role the Discovery is intended to play within that vision. We don't know how old she is, what role she plays, where she is stationed. In fact we know pretty much nothing about her other than she
might be stationed in an asteroid and has a vaguely klingon feel to her appearance.
Clearly he designed the ship that way for a reason and without more information it seems premature for people to judge the design on aesthetics alone, especially when the fanbase has accepted starfleet vessels which differ from the "classic" layout to a far greater extent.
