that would be awesome, I tried that, but somehow ended within an endless loop of dep mismatches and after fiddling for way too long just gave up.

I think it would be really nice to have svelte 5, but not mandatory at the moment so I tried to focus on way more features that are still needed.

But if you want to tackle that, that would be awesome!
