There was a problem hiding this comment.
Safest way is
if (isset($this->output) && $this->output instanceof \Symfony\Component\Console\Output\OutputInterface) {
Because the property is not typed hinted and it could be of another type and because it could be accessed before initialization.
This is valid also for the other changes.
PS.
I forgot to hit submit review before merge...
