A new proposal has been announced: Change type folding to take self by value #371. It will be announced at the next meeting to try and draw attention to it, but usually MCPs are not discussed during triage meetings. If you think this would benefit from discussion amongst the team, consider proposing a design meeting.
@T-compiler: Proposal #371 has been seconded, and will be approved in 10 days if no objections are raised.
implemented in https://github.com/rust-lang/rust/pull/78313
