Way forward for open-plugin-spec #4

Hi team,

First off, amazing work on this! I would love to see open-plugin-spec adopted as an industry standard.

Are you already engaging with the major harness vendors? If so, do you see any interest on their end in solidifying this as an open standard?

For context, my motivations are tied to my own open-source project: https://github.com/rp1-run/rp1.

Even if the vendors do not move forward at this point, I am very tempted to build a cross-harness extractor based on this spec to support my project.

Please let me know if there is anything I can do to contribute. I would love to get your thoughts on the best way forward!
