Do we still need `vue-style-loader` ?

`vue-style-loader` haven't update for a long time. Since `style-loader v1.x` published, I use `style-loader` to replace it, everything works fine. 

Question is:

- Can `style-loader` work in `vue-ssr-project` ?
- Can we use `options.injectType` of `style-loader` instead `options.manualInject` of `vue-style-loader` ?

My answer:

I don't know, because I don't use SSR for now.
