Personally, I didn't release my dream address until I was completely done and satisfied with my island; I just felt more comfortable having a 'full product' for people to look at.
With that said, I did make some changes later on, which was to be expected. But I think it's good to have a 'base model' for your island that you more or less are going to stick with in the long run; the only reason I made changes to it is because I got bored and felt inspired to implement something new for a change.
So, technically, your island can/will always be a work-in-progress or a draft. But that's just my experience and preference. Do as you please!
