Google.com Using The Deprecated <center> HTML Tag

Alright so this is kind of a nerdy thing but when I was working on improving my site's speed performance. I went on Google.com to check out their HTML page source to learn from their web practices. To my surprise, I noticed the <center> html tag was being used to center the Google Logo and search tools. This HTML tag is not supported in HTML5 and is a deprecated HTML tag. Every web developer discourages its use and scream "use CSS instead!" I hold Google to the highest standards and it was shocking to see that. I am in no way criticizing Google at all, I just kind of find it funny. I am sure there is a strong reason why the Google engineers decided to use that tag. People say duct tape is an engineers best tool so I guess HTML tags used for semantic value is the duct tape for web developers.
Now, half way done writing this post, I think I am probably the only one making a big deal out of this. Nevertheless, I just thought I would share it with you guys. Feel free to post any thoughts below
