Safari, macOS Tahoe: tabs bar attract too much attention

On pages with a clean design and white background, the most eye-catching element becomes the new rounded tabs bar. Previously, Safari felt like a neutral tool I used to access content. Now, Safari itself visually competes with the content for my attention.

It would be very helpful to have a setting that allows me to make Safari more utilitarian, so the focus remains on the websites I’m viewing rather than the browser UI.
