It's still an ugly design IMO, no matter how well anyone presents it. And having a huge glass dome on the end of the dong is just asking for it to be shattered in combat.
I understand that Traveller is supposed to be Space Opera, so yes, you're concern is valid.
But I think given the ranges of Traveller space warfare, the actually the issue would be moot. Star Wars Star Destroyers are vulnerable because of their easily identified bridge structures - combat in SW takes place in visual range and apparently you can reasonably easily aim at the bridge.
On the other hand, real-life ships such as even World War 1 dreadnoughts or modern-day aircraft carriers - the bridge or command structure is visible, but it isn't particularly vulnerable because of accuracy - WW1 gunfire at "naval" ranges just wasn't accurate enough to aim for the bridge. Similarly, modern-day anti-ship missiles don't really aim for the bridge, either (they may happen to hit it, but they don't aim at it - there's better stuff to aim at).
Although various writers have stated canonically the vulnerability of the glass dome bridge, I don't think this would "actually" be true; Traveller space combat doesn't (or didn't in previous editions) let you "snipe" for various parts of a ship at the long-ish starship combat ranges (nor should it at 5,000km+ ranges). It highly feels like one of those things that sound intuitive but actually aren't. For instance, during WW2, everyone thought that sending a large number of smaller convoys would reduce losses to U-Boats, but an analysis of statistics showed, no you're better off just sending a few larger convoys - similarly during the same era, putting a huge number of machinegun positions on bombers didn't actually save bombers and lives, instead many of the positions didn't significantly contribute to the defense so those extra men were dying for no reason.
This sounds like it'd be one of those situations.
When your hits are randomly hitting various parts of the ship with areas close to the center of mass getting more hits than the rest of the ship, we'd find that the risk of being on the bridge would actually not be significantly greater than being anywhere else in the ship, and perhaps actually be less than some parts of the ship. Or some statistician showed that most cruisers are actually taken out in a single catastrophic spinal mount hit, so the danger of the "exposed" bridge is actually negligible. As an IMTU thing, I'd say that the bridge was moved because of a perception by the crew of danger (which would lower morale) as opposed to a true danger.
EDIT: I should add that, yes, it's a pretty ugly spacecraft. For me, it lacks the "so ugly it's kinda cool" aspect of the Far Trader. It's just ugly. It looks like a cheap set for a low-budget 1970s or 1980s sci-fi show made from a take-out (take-away for those in the UK) plastic bin for a side salad or capped plastic tray for strawberries, glue a woman's deodorant tube to the bottom, add gubbins, then spraypaint the entire thing white. (Given that Traveller seems to occasionally want to cultivate that vibe, I guess it succeeds.)
