+SG10 (is it too late to rename our document to SD10 for consistency?)

The paper just adds support for incomplete types to reference_wrapper. What code would you write based on the presence of that feature?

The paper seems to suggest bumping __cpp_lib_reference_wrapper, but we didnt have that one before, and I'm not sure it makes sense to introduce for this case?
