That's a great question :-)

In general, this isn't a new problem per se, as backend API changes can similarly break different clients that have been cached. Or when you deploy client code and the code-split chunks have changed. It's true that with this approach it likely becomes a more common problem.

One way to solve this is immutable deployments where the server runs the version of the code that the client is on. Many providers already do immutable delpoyments so there's possible integration there. It could also have some kind of a fallback where a coarser refetch is triggered when the versions become incompatible.

We expect that hosting providers will be innovating in this area in the future, too.
