I run security teams for startups with my current firm, Latacora, which is me and 5 other veterans of security firms. Our clients engage with financial services and with regulated environments (like HIPAA/HITECH and the standards and practices of large health networks). Before that, I founded a company called Matasano, which for almost 10 years was one of the largest software security firms in North America. Unlike at Latacora, where our clients are all startups, Matasano's clients ran the gamut from startups to big tech firms to international banks, trading exchanges, utilities, and pharmas.
With the exception of the military, which I on principle won't work with, there's probably no regulatory or audit regime I haven't had experience with.
I say all this as lead-up to a simple assertion: I have never once seen an auditor push back on bearer-token API access. It's the global standard for this problem. If you knew how, for instance, clearing and settlement worked for major exchanges, you'd laugh at the idea that 128 bit random tokens would trip an audit flag.
In case tptacek doesn’t respond, I’d like to give a (hopefully helpful) answer in the aggregate sense: many members of the information security industry refuse to work with the public sector (read: military and intelligence agencies) for reasons of personal ethics. They typically dislike the privacy-antagonistic ends to which they consider their skills, software or inventions would be used. This is particularly the case with many cryptographers, who could walk onto jobs or lucrative contracts with the NSA, but who would never even consider it.
I haven’t spoken to tptacek about this directly, so I want to make it clear I can’t elucidate his specific concerns. But the broad strokes of his principles are very common in the industry, and typically stem from a disagreement in how the government approaches security (philosophically speaking).

tl;dr: No.
