Common sense in medicine prioritizes doing no harm.
I can provide other notable examples if need be. The bottom line is that all parties need to be confident that the expected benefit of a test or procedure outweighs any expected potential harms. Having multiple layers or peer review is one way to ensure this.
I work on clinical trials of "black label" (potentially lethal) agents in patients that typically have no other options. Our pages can be 70-100 pages and we are doing this in our "spare" time (Ha! Ha!). I don't think it's unreasonable for a massively capitalized private company to produce documentation at least up to this standard.
It really isn't much to ask, especially for an existential venture like this (something -- anything! -- trustworthy to recover the tremendous amount of credibility they've lost.)
Other companies had no problem writing a suitable protocol. Why should peoples' safety be compromised just so that an untrustworthy company can enter the market?
