Do "picked localized routes" result in prerendered routes?

[nachoadjust]

Hello! 👋

I was wondering if setting the localized routes in pages as shown in the docs result in these routes being added into routeRules as "prerender"?

---

Objective:
I am attempting to statically generate (now called prerender I believe?) the routes defined in each page definition of defineI18nRoute.

My assumption was that if I declare defineI18nRoute in a page:

// ./pages/blog/index.vue
defineI18nRoute({ locales: ['en', 'ja', 'zh'] })
...

Later those routes would get "auto-injected" into routeRules as prerendered routes.

Something like:

// nuxt.config.ts
export default defineNuxtConfig({
  ...,
  routeRules: {
    '/**': { isr: 60 },
    '/': { prerender: true },  
    ...[LOCALIZED ROUTES ARE AUTOMAGICALLY INJECTED HERE]
  }
})

---

What I got so far:

• I see the localized routes generate as expected if I run nuxt generate (they show in the build logs)
  but they don't when done via nuxt build (they don't show in the build logs).
  In my case my project is built using nuxt build.

• After running nuxt build > in runtime: tho the localized routes are not prerendered I see things behave as expected.
  A page 404s if the locale in the url is not matching any allowed value in that page's defineI18nRoute.

  mysite.com/ja/blog/ # works!
  mysite.com/es/blog/ # 404 (which is expected, cos we only allowed 'en', 'ja', 'zh')

Hope all of this makes sense!
If anyone could help me understand the behaviour I should expect from localized routes when doing nuxt build and if it makes sense to prerender those routes (and how 😅) I'd be very grateful!

Thanks in advance!!
