Should Raven's Cove be e classified as a main island?

[KeeperOfTheCode]

It doesn't seem to be a 'main' island. Main islands host quests of all sorts, along with towns (thriving), and shops (usually with living owners). No, Raven's Cove is a quest! The whole island is a quest! Nothing else of interest there. Ghosts that can't be killed on the outside, ghosts that can be killed, but can only be reached via said quest, along with a one-time boss battle (is it one time?).
