Yes, it forces the links to libscrypt* instead of libdescrypt*

I don't quite understand the question. You are correct in that the DES
dist. is required for the crypto in 4.x, which sets up the libcrypt links
to libdescrypt*. And yes, it would be nice to have the ability to select
the default crypto mechanism (patches are gladly accepted).

Yep, from /usr/src/Makefile.inc1:
.if exists(${.CURDIR}/secure) && !defined(NOCRYPT) && !defined(NOSECURE)
SUBDIR+= secure
.endif
among other places.
