I don't believe they are crucial.

But eventually this needs to be explained (whether in courses, books) or 
understood by people that just want to read and understand the specs.

Given IPv6 is mostly all about addressing, and that have a "scoped 
addressing architecture", it'd be nice to be able to agree on what scope 
actually means -- in a way that such definition works across specs -- or 
simply get rid of this and any other problematic terms.

Thanks,
