Commonly used doesn't imply 'good' design. On the web, popular patterns are unfortunately often the worst choice for both usability and performance. Web design profession doesn't have any quality bar or certification.
If you like this behavior it's your site, do what you like. As a user i hate it and would like a way to avoid it.
As a web professional and user, I wholeheartedly agree. I would much prefer a consistent, nav bar that doesn't show/hide when I scroll up/down. I find it far more distracting than useful.
