Our plans for native CSS nesting support are described in this blog post.

[ggedde]

in the blog post you mentioned it states "We will add support for parsing plain CSS nesting in .css files. This nesting won’t be resolved in any way; Sass will just emit it as-is."
When will this be supported? Or how will it be available?

Supporting nesting in plain CSS is tracked in sass/sass#3524.
