WG21-P3179R9 (tracked in #5610) fixed preconditions for the following algorithms, for both std and ranges versions:
copycopy_ifmovetransformreplace_copyreplace_copy_ifremove_copyremove_copy_ifunique_copypartition_copyset_unionset_intersectionset_differenceset_symmetric_difference
I think the precondition fix should be treated as an LWG DR as it probably superseded LWG-4262 (as noted in #5683 (comment)). Perhaps we should investigate whether our precondition checks (if any) are still correct.
