All depends on the presentation. Matt Jeffries was a genius by realizing all the ships important stuff should be accessible from the inside. That concept is very realistic and futuristic. But heaven forbid a smooth hull ever be depicted to today's audience. "What, no greeblies? That doesn't look futuristic."
DSC's target audience isn't going to care about any of that. Just like they're not going to care about how the Klingons look. They're going to care about good storytelling and memorable characters.
