I see a lot of people voted disagree, but I don't see why. The menu doesn't restrict you to play without the texture pack: it's literally one click to not download the texture pack. As for the NPC, you always get the menu to select. In my opinion, this would almost be a bug.
The Lucky Island texture pack is a whole other game experience CubeCraft designed carefully. Even though some people don't like to play with the texture pack, they can select to not download it. However, if you are not explicitly given the option, people, mostly for the newer community, will not select the texture pack because of the lack of knowledge. Giving the option is something that's already used, and it is fairly strange it is not in the compass menu. I definitely agree with the suggestion!
