A side note: the run() function doesn't seem to be documented anywhere, is that the case?

That's just for the legacy migration...it will probably have some doc once we have proper documentation in place tho but since it shouldn't be used outside of the migration I don't think it actually needs too much docs

I've checked and it is in the new docs for Svelte 5. They're not available yet, but the function will be covered by docs
