I had exactly the same thought, my wife is doing a Shecodes course and the confirm and alert features are very good simple UI components that require no additional work, it allows beginners to piece together a complete experience without having to build a whole UI stack. And letting go of beginners... removing them seems like the reverse of what we need to do here. They should be improved to the point that no one needs custom confirm dialogs anymore. It makes no sense at all that we require so much reinvention of the wheel on the web, even down to these ultra-generic features.
