Something else I forgot to mention ...

The point of -CURRENT is to make sure everything works before it becomes 
-STABLE and -RELEASE.  Not building significant components of the system 
ensures those components don't get tested.  This includes the actual build 
process, as well as the underlying profiling functionality.

As a FreeBSD developer, you eat the cost of compiling everything.  As a 
FreeBSD developer, if you are concentrating on a specific area at a 
particular time, turning off un-related parts of the build might speed 
things up for you.  As a FreeBSD developer, you know how to do that.
