I am delighted that you noticed the piece framework design. The connectors have no dependency on the core. We are currently working on releasing each connector as a separate npm package, which can be utilized in any codebase. If this is useful for your particular needs, or if you have any suggestions/ questions, please let me know. If you are interested join our discord, we do the announcements there.
