That's not exactly it, but the idea is right.  isnetconn() (previously
issock()) has been around since bash-1.13.  If I had to guess, I'd say
late August 1992 or 1993.  It wasn't inherited from csh.  The original
requests were along the lines of having something to set the remote
environment when running rsh or rcp. As you can see, this long predates

As ssh became more popular, there were different ways to accomplish the
same thing (e.g., put BASH_ENV=startup-file into ~/.ssh/environment), but
there were still requests to leave the feature in bash.  It's still there
