📚 Description

This is actually a breaking change, but we have marked this functionality a deprecated before stable v8 release, so I don't think it should be marked as breaking? 🤔 I'm not sure..

The deprecation of using nuxtI18n with definePageMeta was a bit soft, as we kept using the same key internally for setI18nParams I can imagine there may have been users ignoring the warning. So I added a similar warning that should only be logged in a development environment and changed the nuxtI18n key to nuxtI18nInternal, this will break the functionality for projects using the deprecated functionality and better communicate that this is an internal key. At some point we may or may not move away from using the meta key on routes.

Thank you!

I had planned to drop features in v8.1 that I had marked as deprecated prior to the v8.0 release.
However, nuxt i18n versioning is in semver, and according to semver policy that is equivalent to a major change.
And also, the recent OSS semver for automatic tracking tools like renovate and dependbot, as well as release tools.

So I believe that if we drop deprecation, we should release as v9.

There may be other deprecations in nuxt i18n.
I think we should pickup all of them once and drop them and release v9.

I agree, I'll label it v9 and set it to draft. It's good to be careful with breaking changes, I think with some planning it can be combined with some other changes.

Maybe I'll open an issue/discussion for v9 in the coming days to track which issues/changes could be included so users can give feedback or suggest changes.
