This is a reasonable next step, since trivial relocation, as defined by C++26, will differ significantly from the de facto implementation practice that has been in place for years.

This detection has (IMHO) huge applicability and also offers a direct upgrade path for libraries that today have their in-house definition of "trivial relocation" likely meaning "bitwise", and want to avoid possible surprises if they just switch to C++26's definition of TR.
