Since /home/ian/foo/BSDmakefile is not building something that is part
of  the freebsd world, or the freebsd kernel, then according to that
paragraph, a build using that makefile should not be affected
by /etc/src.conf.

I don't see any way to interpret the paragraph you cited other than
meaning that src.conf is intended to affect only world/kernel builds.  I
mean, it says that.  It says *exactly* that.  It even mentions the
existance of the file that should be used for settings that affect
things outside of world and kernel builds, to help emphasize the
difference with how src.conf is intended to be used.
