Deprecate `setRequestLocale` in favor of `next/root-params`

[amannn]

As mentioned in the static rendering docs, setRequestLocale is intended as a stopgap solution to be removed at some point. I've started a discussion for the relevant feature on the Next.js side here: vercel/next.js#58862

If you'd like to help simplify the usage of next-intl, please join the discussion there and upvote the comment!

Some components need to use "use client", and I want to output static files. There is a conflict between the two. How should I solve it?

You don’t need to call the function in client-only pages.

I'm curious about whether calling setRequestLocale at the top level app/[locale]/layout.tsx will apply to the whole app or not?

When exporting generateStaticParams at the layout all sub routes are affected by it.

Unfortunately not, please see the corresponding docs: Add unstable_setRequestLocale to all layouts and pages. It might work in some cases, but there's a race condition. To work reliably, you should add it to every layout and every page that you wish to enable static rendering for.
