I'm actually a bit surprised people are bringing this up now, since when I announced the plan to make these changes, I said that nothing would be changed that would break anything

I think people read this as "nothing would be changed, period."

However, you did make substantial changes to the specification (or else the whole exercise would have been pointless, I suppose, and you couldn't have claimed that WSGI is now Python 3-friendly when it previously was not).

So this is essentially a new version of the spec. As PEPs themselves are not versioned (unlike, say, ISO standards), Guido insists it ought to get a new PEP number. Then, people declaring compliance can identify what specification they actually comply to. Declaring compliance to PEP 333 as-of-last-week-but-not-as-of-today is now difficult. This particularly puzzles people some of the existing WSGI servers are now incompatible to the PEP, when they still were compatible last week.
