I saw that project reserves a part of tokens to encourage the community to participate in the development of the project. It is a good idea. There are many excellent experts who can help you build your products.
I think it is not bonuses for third-party developers. The team must have its technical experts. Probably it team says about finding new team members.
In any case, interested parties will be able to turn to team with offers of assistance in software development. I'm not one of them. Project interests me as an investor.
