Thanks for this!

It ought to be a lot easier than this detective-work to discover this plan. Like, we should probably all know about it, and stop using these user-agent modals now working to replace all use of them?

(rails-ujs, for instance, still uses window.confirm for opt-in "are you sure" on form submissions. not sure what a good replacement is honestly. This is something I would hope to see people discussing and figuring out...)
