How about specify Debian version in apt line, not its codename

Some of Debian users don't know about its codename, they just know it's a stable version or Debian version.X (major version) like Debian9, and sometimes confuse with apt line ("hey, what does 'stretch' means?").

We probably can improve it as providing symlink in repository as below.

$ cat /etc/apt/sources.list
deb http://ftp.jp.debian.org/debian/ Debian8 main contrib non-free

It's so simple - isn't it? If you have a comment, please post to BTS.
