Is there a plan to integrate fenced code blocks in rst?

I use rst heavily for my documents and slides for teaching which in turn 
include many code blocks. Is it possible to use code blocks in rst 
without indenting them, e.g., like *fenced code blocks*?

The reason is, it is cumbersome to copy and paste indented code blocks. 
There is an extension for Sphinx for this purpose [1]. Is there a plan 
to integrate fenced code blocks in rst?

I am not subscribed and would be happy if you could CC me.
