Performance matters - a lot. It's often overlooked because its effect on users is more unconscious than consciously noticed, but even small speedups greatly affect user motivation, as measured by any number of blog posts about "page load time" and "conversions". However, "instantly smooth transitions" may not require using JavaScript. According to the blog post, GitLab observed a performance increase after ditching Turbolinks[1]. Indeed, sites that use JS to speed up page loads are often compensating for what would otherwise be an excessively slow load, due to having lots of scripts or whatnot. And that's only a partial fix: the user still experiences that slow load whenever they come in from an external site or open links in a new tab/window. If you can make "real" page loads fast, you avoid that problem. [1] ...though it doesn't seem to have been measured very scientifically - to quote from the pull request: "I thought I noticed that pageloads were a lot more snappy, and one other reviewer said the same. Not the most rigorous way to test performance, but it helps."
