It seems that the return type of <=> for integer-class types is not specified consistently with other comparison operators. Even P2393R0 has ignored it.IMO strong_ordering should be added to 22.214.171.124 [iterator.concept.winc]/(5.3), and three_way_comparable<strong_ordering> should be added to 126.96.36.199 [iterator.concept.winc]/8.
[2021-07-31, Daniel comments]
The upcoming revision P2393R1 will provide additional wording to solve this issue.
