Not saying offline-first apps have no interest, they totally can have some.

But in more than ten years, offline mode have never been a requirement on any of the projects I worked on.

What I’m saying is that offline mode is just a feature like any other and it’s one with a huge cost in architecture complexity.

And, although it’s just my own opinion, I think if you want to be offline first, odds are that better stacks than the web exists for those needs.
