That does seem more flexible to me, but I have heard people argue that
accessibility through add-ons and plug-ins was not acceptable (I'm not
quoting anyone on that, however). Are there people in the WG who feel
that the browser must conform 
  a) without the possibility of adding software to some "core" user
     agent (if such a thing exists), and
  b) conformance must be based on default settings (for those parts
     of conformance that are configurable)?

Yes, I agree.
