In general the man pages do not care what OS and manual they are shipped with, so they don't get to choose the names of them. We were tempted to do so, as we had inconsistently chosen OS names for the mandoc and man-db/groff implementations. Since this has been rectified since, we can just drop this boilerplate from the man pages.
