I'm with you Justin on the sticky navigation. I too have a strong dislike for the claustrophobic feel of sticky navs. At least they did not implement it on mobile, where one has very little excess vertical space.

Thankfully sticky navigation I would say is very much on the way out. In fact it's been a long while since I've seen a new website with one. More often these days I see websites utilise modern solutions like Headroom.js (https://github.com/WickyNilliams/headroom.js/), which has nearly 11k stars on GitHub. I've used it as well for at least 5+ years. Since users don't need your menu while scrolling down, i.e., interacting / reading the content, and only need navigation when scrolling up, "scroll up bar" style navigation like Headroom.js I think has become the go to sticky menu replacement.

But it does concern me that the WP team responsible for this is so much behind the times. And because Wordpress.org is such a popular site I sure hope their implementation of a sticky nav doesn't bring it back into fashion. The horror! :)
