There seems to be very little in the way of deck hardware; e.g., bollards, chocks, capstans, handrails, etc. Presumably, these are either retractable or moveable. It also seems to accommodate very little in the way of topside manning by watchstanders, etc. I’d miss not being able to hang out on the fantail with a cup of coffee at the end of the day...
As many protrusions as possible are removed or retractable. Makes a big difference in stealth and radar return.
I expect in that large deck house, there will be ample place for watch standing.
Also, aft on the helo deck. With railing that retracts, they can stand watch there and particularly on the inset decks and houysings along the hull as necessary.
You can see some of the possible positions along the hull, in the bridge/deck house, and on the fantail and helo deck in this pic:
