Yes, any group can soft or hard fork. This group is the first group that has this much traction behind normalizing consensus-level behavioral gating for "safety".
Like I said, if you do constrain at consensus, you normalize control at L1 and open the door for future parameterization under "safety" banners.
A soft fork that prunes behaviors creates a focal point (maintainers + large clients + pools) that can be lobbied, sued, or regulated. The more "safety" is cited, the easier it is to extend the scope (AI-safety, biosecurity, financial integrity, carbon).
Lawmakers don't need new statutes; they can simply point to "Bitcoin already excludes Y", and press for Z (e.g., "exclude sanctioned payload types", "restrict non-KYC script paths"). You've demonstrated precedent and capability.
So I never said that any group can't soft or hard fork. I am writing about this group because the consensus changes they've proposed are backed by a lot of Bitcoiners and there are pros and cons to this soft fork. However, I don't think most understand the difference between consensus rules and policy rules.
