No one is forcing you to upgrade, Svelte 4 still works just fine? Svelte has had basically no major API changes since 2019, that's a better part of a decade. And with this new architecture change, they released a sophisticated codemod to do most of the work of updating for you.

Great until your dependency scanner picks up a vulnerability in the framework or a dependency that can't be upgraded without breaking v4, no exemptions can be given and the only updated version is 5. [1]

If it's already end of life you can fork it and upgrade the dependency. You'll miss nothing. This is only difficult if you need to maintain changes upstream, but that's not the case here.

Security support lifetimes make sense for a widely used language or runtime, but not really a frontend web framework on the most backwards compatible language you can have.

In fact, you can still use Svelte 4-style components with Svelte 5, even in the same project.
