does it scale to have 1 person approve of all phobos additions?

I have never used DUB, but as I understand it, it will 
automatically bring down modules that are stored in gitub or two 
other git hosts (but not SourceForge for some reason). With that 
kind of functionality, it seems that inclusion in the standard 
library becomes much less important for a library. Rather than 
being included into Phobos, modules could be sanctioned/blessed 
in some fashion by dlang.org beyond their inclusion at 
code.dlang.org . Such as having their documentation on dlang.org 
(or wiki.dlang.org with a link to the wiki page on a dlang.org 
page that is for listing "sanctioned modules" or "semi-official 
modules").
