RFC 2044 explicitly refers to Unicode 1.1. Martin seems to think that
the "consensus" is that "utf-8" refers to Unicode 2.0. However, any
perceived consensus is useless unless it's documented. The current
situation is confusing, and invites mistakes.
How did we end up making more mistakes? First, Unicode and ISO made the
mistake of making an incompatible change to Unicode. Now, we made
matters worse by confusing 1.1 and 2.0! How unfortunate.
Also, there may not be much extent Unicode 1.1 data on the net, but
there are installed copies of software that assume 1.1. E.g. Netscape
Navigator 3.0, which uses Unicode 1.1 conversions for KS C 5601 in Java.

Did they also pledge to refrain from re-using the codepoints U+3400 to
U+3D2D in the future?

David Goldsmith's spec allowed for a very regular naming convention,
which could be recognized/parsed. The client implementation could
recognize UNICODE-3-0-UTF-8 as being a new version of Unicode.

Hey, you're betting using *my* money! :-) Just kidding.
