I find this recently added rails default a bit too restrictive, especially because iOS doesn’t allow 3rd party browsers and only offers browser updates via system updates:

> In addition to specifically named browser versions, you can also pass :modern as the set to restrict support to browsers natively supporting webp images, web push, badges, import maps, CSS nesting, and CSS :has. This includes Safari 17.2+, Chrome 120+, Firefox 121+, Opera 106+.
