The figure was not chosen in any highly scientific way.  

It is a figure that is "large enough that nearly every active LIR today 
can get an IPv6 allocation NOW" (having somewhat over 3000 LIRs in RIPE 
land, of which some are not active any more, others have merged, and so 
on), while at the other hand being small enough so that *if* this 
turns out to be a mistake, it means "6000 'IPv6 swamp' prefixes in the
global routing table", and this is something the routers can handle.

Yes, but that would mean 60.000 "bad routes" (if it turns out to be wrong),
that's where the 3x2000 number came from.

It's in the draft somewhere: existing /35s get extended to /32s, no 
questions asked besides "do you want this?".  As far as I can remember,
there was consensus on this point in the RIPE group.
