".... if you use a safety pilot and write that safety pilot's name in
your
logbook, we'd highly suggest that you treat that safety pilot as a
required
crewmember........... If the airplane is high performance, complex, or
tailwheel, that safety-pilot-required-crewmember should have those
additional endorsements, too."

Notice it says "should have those..." It doesn't say is required to.
Sounds like a recommendation not the law.
