header clean-up

Hello,

Would you advise making the header clean-up changes shown here: https://bhoover.com/remove-unnecessary-code-from-your-wordpress-blog-header/

Or is removing any of them going to interfere with GP or GB (or core wordpress functionality for that matter).

I'm thinking mainly from a performance/speed standpoint -- better to leave them in or to add the filters that remove them?
...just trying to do a little clean-up but wanted to check on your insights :)

Thanks!
