For what it's worth, there has been no "insisting" from us one way or 
another. The reason we didn't go with the hardcoded classids was that we 
didn't learn about them until late in the FF3 release cycle, at which 
point switching to that solution was too risky.

However we did think it was an interesting approach.

In general plugins are super hard to get correct. Pretty much any change 
we've made has broken sites. I suspect this part of the spec will have 
be updated once we look through it and compare to our implementations, 
as well as once we deploy whatever changes we make to be compatible with 
the spec.
