Either I completely misunderstand the argument, or I disagree -- strongly -- 
with it. Including bits created and maintained by others into your own project 
is very rarely justified (although done quite often). I don't see, why adding 
(some version of) bsd.lib.mk and friends into every project, that wishes to 
build a shared library on FreeBSD, is any more justified, than bundling libjpeg 
with every graphics application.

John-Mark also just posted a strong argument for using the existing bsd.*.mk 
family of makefiles...

The documentation is, demonstrably, incorrect -- it was incorrect, when it was 
written 7 years ago, and remains so. Because a user of bsd.*.mk /will be/ 
affected by src.conf -- unless he takes special steps to prevent it. This fact 
can not be fixed by a user, the only way to avoid the effect, is to modify their 
own makefile(s).

The implementation of the change may be blamed for this -- if, indeed, there was 
a need for src-only configuration knobs, src.conf should be included, when a 
special flag is present in the environment (put there by src/Makefile), not the 
other way around.

And some of those settings are required for healthy building of some of the 
ports... For example, libreoffice "knows" out of the box, that FreeBSD has 
Kerberos libraries. So, if your world was built WITHOUT_KERBEROS and 
WITHOUT_GSSAPI, libreoffice fails to configure. A simple patch like:

    +.if defined(WITHOUT_KERBEROS)
    +CONFIGURE_ARGS+=       --without-krb5
    +.endif
    +.if defined(WITHOUT_GSSAPI)
    +CONFIGURE_ARGS+=       --without-gssapi
    +.endif

could help, but WITHOUT_KERBEROS and WITHOUT_GSSAPI are set in src.conf and not, 
normally, available to the ports...

So, in my opinion, the manual (src.conf(5)) should be updated to reflect 
reality. Or, if the separation is really deemed desirable (something I, for one, 
continue to question), the implementation (in /usr/src/Makefile and bsd.own.mk) 
needs to be altered to only consider src.conf, when world/kernel are being 
built/installed.
