I'm not sure If we really want to camelize all namespaces, a namespace not necessarily would be :

Vendor\Package\Component\Classname

A package name could be: MyAPP\CLI\CLIConsole, that being camelized would be transformed to: Myapp\Cli\Cliconsole which makes this class completely "unloadable" by the autoloader. Do we really want this?

OK, Then I restore.
