The current version in sets.subr contains:
[3:13pm] 226>grep mkvars.mk sets.subr
for x in $( MAKEVERBOSE= ${MAKE} -B -f ${rundir}/mkvars.mk mkvars ); do
MKVARS="$( MAKEVERBOSE= ${MAKE} -B -f ${rundir}/mkvars.mk mkvars | ${SED} -e 's,=.*,,' | ${XARGS} )"
# make -f mkvars.mk mkvarsyesno
# make -f mkvars.mk mkextravars
Doesn't that work for you? I made that change in 2017...:

Ignore MAKEVERBOSE for snippet makefiles.
