For some it's all about the model and the finished result. For others that kit is merely a means to an end. If someone is by themselves and they can while away a couple of hours in an otherwise long day then that kit has done it's job whether detailed or not. If someone with chronic pain can get a few hours of relief because their mind is focused on building rather than their ailments then I don't care if the final results are good, bad or upside down.
Builders build for various reasons, some are more invested than others. For some it's a passion, for others merely something to pass some time. For this reason I wouldn't be quick to assume that any missing details were "overlooked" but possibly something the builder just doesn't care about.
I think it depends on the context. If someone is displaying a build as an example of their work then they're probably looking for comments. If someone is displaying their work to demonstrate or illustrate an answer to someone's question then that person probably isn't looking for comments, merely just trying to help someone out.
