FR: Separate deps and devDeps after running yarn eject

[iamclaytonray]

After running yarn eject....

Is there are reason why all dependencies are in "dependencies": { ... }? Things like webpack, eslint, and others should go in "devDependencies": { ... }. So, I guess the feature request would be to separate deps based on where they normally go, unless there is an existing option that I haven't seen in the docs.

This is intentional because everything would be a development dependency, and the ecosystem works better under dependencies for things like Heroku etc, see the issue linked above.
