It's a narratively significant alternative that gives Blizzard the freedom to fully use the city for endgame content for most of the expansion.
You not liking it doesn't make it bad.
I used Bel'Ameth as an example as a subzone that became a player hub, not advocating that they should just copy it 1 to 1 and avoid utilities.
Bel'Ameth lacking them does not prevent Silvermoon from having them, especially when Silvermoon already has them and Blizzard doesn't need to spend any additional effort in adding them or creating a space for them.
