Let's change order, because we want to expose it for any plugin developers, not every generate js schema (so check should be last, optional)

Missing that, let's do it futureDefaults === true && mode === "production" ? false : true, catch all problems for development mode is good DX, for production mode I think we don't need it, but to keep compatibility and don't break behavior let's do it for the next major release

Let's change order here too: value, schema, options, check, the last too are optional, options are more often used than check and we can merge

It’s not working properly for multi-compiler support.

Hi @bjohansebas , this hasn't been released as an official version yet, so I'm not sure if you're using the version from this pull request.

I’m using the version from this PR, and yes, I know it hasn’t been officially released. I was just pointing out that multi-compiler support is still missing so that webpack-dev-middleware can use it.

@bjohansebas Oh, the multi-compiler was missing. I'll add it now. Thank you.

I've refactored the code to simplify the logic, also with new API we will reduce count of initial require and extra calls, no validation until you really have asset/css/etc module in your code (i.e. when we run createParser/createGenerator), still WIP on plugins
