To explain further, RGB is a technology built around the concept of client-side validation, and the latter, by definition, is a much more restrictive environment than blockchain or classical programming ones in terms of protocol updates and such, making things like 'MVP' impossible and making no sense. At the very beginning of RGB active development back in 2019, Peter Todd made a strong suggestion that was accepted by all involved parties, that the protocol will be released as one version and this version would be final. If some additions or changes will be required, due to the client-side validation nature of the technology, it will lead to creation of a whole new protocol, not-compatible with existing version. So, there are no plans (and in fact - not technical possibility) to have an MVP of any sort and adding different functionality afterwards.
