For what it's worth, I see nothing wrong with "excessive" use of names paces. I would actually argue this is a good thing. It makes the code more clear and concise in my opinion.
I think it just comes down to a matter of preference, and probably has a lot to do with how Flex is used. Even for relatively simple projects, I will create a custom component set with their own name spaces. I also have projects that use MXML without touching a single class in the Flex framework. For me, the value of Flex isn't in it's component set, it's the constructs it provides for creating a solid application architecture. MXML works great for for me how it is now. All the Best, ~Aaron
