I installed new clean symfony project using symfony/skeleton reposiroty and after that installed bundle. What I propose to change:

• move symfony/stopwatch to required section. Because section require-dev is totally ignored when bundle is installed in project and we have to force this package to be installed. In symfony/website-skeleton it's installed by default.
• replace twig/twig with symfony/twig-bundle. We're registering DebugExtension as twig extension using tag twig.extension and this tag is handled by symfony/twig-bundle. This change will provide us in dev more real packages as it is in real symfony project and will give us possibility to write more accurate tests :slightly_smiling_face:
