[Feature] Have a special flag to enable experimental features

I feel we’re closer than ever before on getting CSS sourcemaps functional for which I’ve been working on CRA fork that so far holds up to issues caused by previous attempts at this problem (see https://github.com/facebookincubator/create-react-app/pull/591#pullrequestreview-463675)

PR for which will be up very soon.

This PR will replace style-loader and new setup will handle things differently. Considering that as well as react-hot-loader or #2304 , these are clearly new windows to awesomeness and bugs.

So how about CRA published with new features (even unstable) included that can be enabled by passing flag to yarn start?

For example: yarn start --rhl --css-maps

Thoughts welcome

@NeekSandhu I don’t think we’re going to be adding flags any time soon [as @viankakrisna said], and I believe @react-scripts-dangerous is the closest we’ll get to a “experimental” version of CRA.

@Timer I was aware of bot and have to say it’s really awesome. But the main reason behind this issue and my previous PR #3163 was getting as many people (brains and eyes) as possible aware and involved* by bringing new things to forefront instead of being a dormant PR.

But again, I understand the disruption of design philosophies this will cause as stated by @viankakrisna
