Matthias Noback has shared a few things he doesn't like about Symfony bundles, the drop-in components that easy extend Symfony-based applications.

This article could have been titled “Ten things I hate about bundles”, but that would be too harsh. The things I am going to describe, are not things I hate, but things I don’t like. Besides, when I count them, I don’t come to ten things...

Instead of ten, there's five things on his list of "hates" about bundles and their handling:

• Bundle extension discovery
• Naming conventions
• Registering service container extensions yourself
• Naming conventions, part two
• Duplicate knowledge: the extension alias

For each section there's an explanation and sample code where needed to illustrate the point.
