https://v8.dev/blog/jitless https://v8.dev/blog/jitless says that while some benckmarks can be 80% slower without a JIT, real world performance in the YouTube web app is more like 6% slower. To be fair that probably doesn't rely on that much JS, but it would be totally feasible to use a browser without a JIT even with modern web apps. Edge has a secure mode that disables the JIT. Of course, the proper solution would be to allow 3rd party apps to use JIT, but allowing 3rd party engines without JIT would definitely be better than nothing
