+1 but maybe should we just follow Symfony's best practices (even if I don't like this one) and extends AbstractController as well as changing __invoke to another name.
It will probably make this documentation easier to understand for users used to "the Symfony way".

WDYT?

Why not for the AbstractController. I'm not so sure about changing __invoke though, we would need to reference the method name in the controller attribute and we would lose the easy way to only use the FQCN.
