Impressive that you were able to scribe this much while talking!

I would emphasize the following three segments:

I don't know if I meant to use the word "reference" or rather "suffix", 
so I'll rephrase this carefully:

If you see the following values:

alpha:beta
gamma

and you ask someone who's done any amount of markup, I suspect most will 
tell you that "gamma" is more like "beta", in other words, "gamma" is an 
unprefixed value, where "beta" is prefixed with "alpha." Very few people 
will tell you that "gamma" is like "alpha", only un-suffixed.

I know you *can* make the rules work the other way, but that goes 
against existing practices and even against the way we used to think 
about this ourselves, since we always talked about "unprefixed CURIEs" 
in RDFa 1.0.

In short: I think this will be very difficult to explain to people, and 
the value is not particularly high.

So regarding consistency:

and the design principle here:

Hope this helps explain my point of view. I see little benefit to 
importing prefixes, and significant potential for confusion in exchange 
for that tiny benefit.
