But we do have proposals which include std::default_copy (p0201r6 & p1950r2) which is as close of an analogous use case as I am aware of. Note we use separate types for allocator support in this case.

What would it do?

std::default_delete can be used as a deleter to std::unique_ptr and other
smart pointer classes (and is the default). There's no such thing as an
allocator parameter to those classes.
