One of the major benefits of application-specific blockchains is sovereignty. A decentralised application is an ecosystem that involves many actors: users, developers, third-party services, and more. When developers build on virtual-machine blockchain where many decentralised applications coexist, the community of the application is different than the community of the underlying blockchain, and the latter supersedes the former in the governance process. If there is a bug or if a new feature is needed, stakeholders of the application have very little leeway to upgrade the code. If the community of the underlying blockchain refuses to act, nothing can happen.
