The ABI break highlighted in R2 (when applying the feature to existing components) needs LEWG visibility.

According to the author, this paper is a subset of P1631 Object detachment and attachment #551.
P1144 Object relocation in terms of move plus destroy #43 is more ambitious than the present paper.

P1029R2 Move Relocation: Design Feedback

Champion: Niall Douglas

Minute Taker: Ruslan Arutyunyan

Start Overview: 07-17 15:19

Start Polling: 15:26

POLL: We understand and accept that = relocates changes the ABI of a type, and thus we will be unable to apply this feature to existing standard library facilities (such as unique_ptr) or remove it from new facilities without accepting a standard library ABI break.
