/usr/src Makefiles  use MK_ internally, but users are not supposed to 
touch them. That's why /usr/src/share/mk/bsd.own.mk has a lot of code to 
convert WITH_/WITHOUT_ variables to MK_ form, applying suitable defaults 
for each architecture.

/usr/src/release/Makefile seems to be a special case, and sits over the 
normal /usr/src/... Makefiles, hence it's use of WITHOUT_ forms.

I've no idea about -CURRENT, I never use anything riskier than -STABLE. 
You'd be better off asking about this in freebsd-current@
