I started work on the cabin, gluing the adjoining walls. What a horrible fit. I loaded the joins (not shown in the image) with sprue-goo to try and blend the corners into a nice round profile. It will be tricky sanding near all the detail.
In some fairness, I have seen fishing vessels with that sort of fit to cabin structures.
This gets us back to what you were speaking of above. That this is a repersentational sort of thing. The "flaw" in rivet counting is that one can be too accurate to prototype. And, if the common viewer is not familiar with the prototype they may be sore pressed to recognise the difference between "accurate to prototype" and "sloppy modeling."
Thus, we, as modelers, have to find that happy middle that suits each of us best.
So, as a for instance, the upper cabin level probably would have had a grab rail, about 36" above the dek, this would be a bar from 0.75 to 1.5 inch diameter, stood off about 1 inch from the bulkhead, with a support about every 3-4 feet. On older ships that might be a wooden dowel in bronze fittings, in later ships metal rod or tube, painted or chromed.
Should you add that detail? Dunno. Would be finicky work with styrene rod or brass wire that would want to snap off repeatedly during construction. But, against that, would add detail back where it had been sanded away.
Using one o the star wheel "rivet" tools might be a way to return detail to the rather blank sides of the cabin, too. (Might be handy on the hull, too, for what that's worth.)
This kit is much like it's contemporary Lindberg cousins, you almost been t obuild one out-of-the-box, just to see what's not there; what wants improving; and so on.
And, of course, it winds up a bit like the skylight over the engine room. The number of ways those skylights were made does not make it a simple process. The "classic" look would be 6-8 individual hatches, each with a (or several) deadlight(s) in them.
From the inside:
Now, those hatch might be smaller, 12-14" wide, with a single 46" deadlight. Or, larger, as above. They'd often have guard rails to keep the them from snagging on working gear:
So, the problem is that the variety is endless. Thus, near every option is "correct" (barring having a prototype to follow).
