  "message": "[libc++] Add the __is_replaceable type trait (#132408)\n\nThat type trait represents whether move-assigning an object is\nequivalent to destroying it and then move-constructing a new one from\nthe same argument. This will be useful in a few places where we may want\nto destroy + construct instead of doing an assignment, in particular\nwhen implementing some container operations in terms of relocation.\n\nThis is effectively adding a library emulation of P2786R12\u0027s\nis_replaceable trait, similarly to what we do for trivial relocation.\nEventually, we can replace this library emulation by the real\ncompiler-backed trait.\n\nThis is building towards #129328.",
