Caching doesn't work correctly with latest rc

[max-frai]

Description

You have on landing page link to example which uses "latest" tag in package.json and everything is okay.
When I migrate app to 3.0.0-rc.6 there is a problem with correct caching headers.
With example from landing on production build I see the following headers:

Cache-Control: s-maxage=31536000, stale-while-revalidate

But with rc6 header is:

Cache-Control: private, no-cache, no-store, max-age=0, must-revalidate

Of course, this makes app very slow because nextjs doesn't cache ssr, etc and recalculates everything on each request.

I build a small example with rc6 which after yarn run build and yarn start on main page gives this wrong cache-control header.

Reproduction description

Steps to reproduce:

1. yarn
2. yarn run build
3. yarn run start
4. Open localhost:3000/en
5. Watch Cache-Control header

Expected behaviour

With production build and all default values for caching it should return the following header: Cache-Control: s-maxage=31536000, stale-while-revalidate

I'll move this to a discussion, since this appears to be a usage question.
