Unfortunately I think this is not the case -- it might just be that the async/await issue is getting pushed into the next milestone tag with each release. In the most recent roadmap video[1] Andrew said that the main focus right now is compilation speed, and that async/await specifically was going to take a long time. My memory is that he says something about how it doesn't work well with LLVM and is generally a hard problem that they would prefer to do correctly instead of quickly.
