I you read the thread on NetBSD mailing list I linked to, that was exactly my concern: the spec does not seem to be enough to implement the protocol according to the original author but he seems reluctant to give details.

And I do not consider NetBSD core team as amateur, frankly.

I am not advocating for competing standards. I am advocating for open standards and competing implementations.

Both of your examples point to competing standards: IE6 was a tentative to fork the web standards by Microsoft. The 20 USB form-factors are different connector standards (even if they all implement the same wire protocol).

I have mixed feeling about this: it looks like the author believes only him can implement it right [1].

This not how internet protocols development work. The spec should be enough, including security considerations. And multiple competing and interoperable implementations should be seen as a good thing in my opinion.
