I agree, a lot of the doc comments become redundant when types are specified in type hints.
Note that doc comments for properties are actually not required, as far as I can tell – you could replace:
/** @var LinkRenderer */ private $linkRenderer;
…with:
private LinkRenderer $linkRenderer;
…today!, and no lint checks are going to stop you. I've been suggesting this for new code since we moved to PHP 7.4, which allows these type hints on properties.
