No sufficient participation, sending to LEWG

P2747 (#1438) was recently forwarded to CWG, so P2283 ( #975 ) doesn't add additional concerns for this issue.
No opposition to the direction;

LWG should update the issue (@jwakely @JeffGarland) with discussion of P2283 and the possibility of using ranges::iter_move, make a very short presentation to LEWG at a future meeting of telecon.
