As you rightly say, opinions have changed over the years. At one time,
the apt-get sources lists referenced stable. This is fine, except when
Debian released a new major version and everyone's installed system
broke on upgrade that day
Release names were orgininally a convenience internally: the great
advantage is that these remain constant for the life of a release
from testing -> stable -> oldstable so use of these makes life easier.
_ALWAYS_ read the release notes when moving from one major version
of Debian to another.

One repository for binaries per line: corresponding entry for source underneath.
This isntall had included non-free repositories when asked because I knew that
this hardware needed non-free wifi and Ethernet card drivers.
This line should work while wheezy is the current stable release and until it
drops out of support as oldstable.

It is there, but most people never need to look for the lifetime of one
installed system.
