Do you have a source for "Only one major feature is planned to make its way through C++17"? Wikipedia tells me (without citations) that C++14 and C++17 are minor and major revisions respectively, but doesn't indicate that "major revision" stipulates only a single major change at most.
And there are lots of people interested in other sets of major features.
So who knows if C++17 will include it, and even it does, how long one can use it in production.
Until 2017 many native developers might just had moved into Rust, D, Go or whatever comes along.
Just look how computing used to be 5 years ago.
