Except one thing: AMD Athlon XP processors on Linux are now cannot start the browser at all. I was using GNOME Web (epiphany-browser) on Lubuntu 18 until the latest WebKitGTK update, but since this SSE2 requirement, my computer became unable to use WebKit. So, this is an issue for me. It was working fine without SSE2, pages using JavaScript heavily (like agar.io and slither.io) and even YouTube videos worked just fine.

About one year ago I fixed the hardcoded SSE2 requirement, and it was working great until now.

Here I fixed the dependency on SSE2 last year (now it is a problem again):
