That is exactly the case.  Each CNA is given a pool of a size that is 
proportional to the number of CVEs they publish.  At this stage, we 
probably have 4 or 5 CNAs who can request 100+ CVEs at a time without 
raising much concern.  Other CNAs might only get 5 or 10.  And nobody 
becomes a CNA without having a reasonably large number of disclosures in a 
year.

It seems to me that the average size of CNA pools is rising, although I 
don't have stats.

Accordingly, in the future, there may be a need to change that model. 
The sources-and-products discussion of last year started to at least 
define a starting point.  We have deferred other discussions (e.g. quality 
vs. quantity).

Even ignoring automated assignment, consider efforts like what j00ru and 
Gynvael Coldwind are doing with ffmpeg, or Adam Gowdiak with Java, what 
r0t did in 2005/2006, or what Dimitry Oboukhov person did in 2008 when he 
grepped for /tmp vulns in all the Debian packages about 5 years ago.

These days, individual researchers can produce many more valid vuln 
reports than 10 years ago, and we have many more researchers today.
