It is the same reasoning as with deep filesystem hierarchies and, 
well, any data hierarchies - once the element (module / file) 
count becomes bigger than ~dozen you only really notice things 
you know to look for. Contrary to that deeply nested categorized 
hierarchies are easy to casually to search through if you don't 
know exact module name - just iteratively pick whatever package 
fits the theme until you find what you want.

I remember coding a bit in C#/.NET platform ages ago - it was 
totally possible to find relevant modules without even looking in 
docs, just using auto-complete through suggested package names 
for import. It was really positive experience for a newbie I was. 
At the same time a lot of people have no idea how many cool 
things Phobos actually has.
