Hm, I took another look. I think acutally, our types are fine. The problem is with the types of fluent-vue:

https://github.com/fluent-vue/fluent-vue/blob/fdc1fbcd45053415c55c86b2885534bed26451c6/src/types/typesCompat.ts#L26

export type InstallFunction<TOptions> = (vue: unknown, options: TOptions) => void

FluentVue claims that it needs an options object. It's just that before c513126, the types for app.use() did not reflect that.

This is fluent-vue's bug, so I close this issue.
