I’m aware of questions like this, where people tend to discuss the general Symfony 2 concept of bundle.
The thing is, in a specific application, like, for instance, a twitter-like application, should everything really be inside a generic bundle, like the official docs say?
The reason I’m asking this is because when we develop applications, in general, we don’t want to highly couple our code to some full-stack glue framework.
If I develop a Symfony 2 based application and, at some point, I decide Symfony 2 is not really the best choice to keep the development going, will that be a problem for me?
So the general question is: why is everything being a bundle a good thing?
EDIT#1
Almost a year now since I asked this question I wrote an article to share my knowledge on this topic.
