Closing since Box::leak is stable in nightly and will make its way to stable in 1.26.0.

I was confused why this was allowed to stabilize, but it appears that the bug that made this API unsound was fixed?

The dupe mechanism doesn't work anymore at least.

Should we escalate this to a new issue with P-high?

Nope, just leaving a historical note for anyone else who was confused. Although if anyone knows when this was fixed (and if a test was added?) that would be good to note.
