I only bring up the question about justified vs. unjustified because it's moot. If you publish the standard, "HF21 shall not use big-endian serialization" and you find during code review that it does, regardless of why, it deviates from your standard and cannot be adopted.

Then the release notes are posted, hardfork timestamp committed and tagged to a version number. All that's needed is for witnesses to adopt, and you don't.

Then, let's say the community pulls support for your witness. I would say the community is unjustified in that situation because you posted a standard, you adhered to the standard. If the community was going to pull their support, it should have been when the standards were published.

Anything else seems like a political move after that.
