If browsers introduced a new parsing mode for HTML5, this might be a
reasonable way forward, but it's pretty clear that they don't intend to
do so.[1] The stated goal is to process all versions of HTML with the
same, HTML5, algorithm.

Basically, HTML5 moves us away from HTML language *versions* and toward
CSS-like language *levels*. We should try to formulate our markup with
that in mind.

When the <time> element becomes available, yes, microformats should
prefer its use. But with my microformat parser implementor hat on, I
don't intend to reject use of the <abbr> design pattern once <time> is
available. They'll both work, it's just that one will be preferred. I
can't say the same about the <dfn> design pattern.
