Hi. Runtime config is overriden in runtime (vue componens, pages, composables, server API, plugin, etc) and not the nuxt.config and modules.

However i think it might be a good idea to handle it also for build namespace for more consistent behavior. /cc @danielroe wdyt?

I think this is a good idea because otherwise module authors would have to manually do the same work to get the required env and conform to the NUXT_ convention.

@pi0 I think it sounds like a good idea to me 👌

@danielroe This is probably the fourth "good first issue" label in my issues 😄 But thanks!
