HTTP/2 has been one of my areas of interest. In fact, I've written a few articles about it just in the last year. In one of those articles I made this unchecked assertion:
If the user is on HTTP/2: You'll serve more and smaller assets. You’ll avoid stuff like image sprites, inlined CSS, and scripts, and concatenated style sheets and scripts.
I wasn't the only one to say this, though, in all fairness to Rachel, she qualifies her assertion with caveats in her article. To be fair, it's not bad advice in theory. HTTP/2's multiplexing ability gives us leeway to avoid bundling without suffering the ill effects of head-of-line blocking (something we're painfully familiar with in HTTP/1 environments). Unraveling some of these HTTP/1-specific optimizations can make development easier, too. In a time when web development seems more complicated than ever, who wouldn't appreciate a little more simplicity?
