I think that such a large undertaking should definitely be up to shoghi as it is ultimately under his ownership. I'm OK with the community lifting up and making a "defacto" standardized fork of it but it should not be under the "PocketMine" branding to conflict with the two. If shoghi ever does decide to come back, he should be able to continue work on his project. Note: there's nothing wrong with "forking" -- that's the premise of free open source software. Most of the time when an open-source project is "abandoned" by its creator, forks will supersede the main repository. It's just etiquette to make the fork distinguishable from the origin.
