The subset of the rules that are hardcoded in make(1) is well
documented, although it's much more complex than I would like.  Search
for .OBJDIR in the make(1) man page.  Most of the code that creates
directories or symlinks or sets variables to influence how make(1) will
choose an obj directory is in bsd.obj.mk

In general, yes, almost all man pages could usefully be expanded.  In
particular on the topic of choice of .OBJDIR, I think the documentation
is accurate and adequate.
