Next.js should warn users when they modify minification settings

[Timer]

We should warn very loudly (or even refuse to build) when the user disables minification for a production build. I think it's best to start with a warning.

We need to check for minimize to be false, or an empty minifier array.

Follow-up: what other properties would be good to ensure users aren't configuring by accident?

I would love to have separate warnings for optimization.minimize and optimization.minifiers. The former is worse since it also disables Webpack's optimizations for NODE_ENV, module concatenation, tree shaking etc.
