Is there a final decision about rvalue references?

Background:
Is it still worth finishing and submitting a PR for 
https://issues.dlang.org/show_bug.cgi?id=11529 ?
I did some experiments on how to fix this and then moved to other 
stuff. Now I have time for a second try, but fixing this if 
rvalue reference will be allowed in future is waste of time.

Sorry for hijacking this thread...
