Isn't your proposed solution an expansion?

So you are saying that users care if a specific feature is implemented
by wget or if it is done by the shell?

wget http://rahulprasad.com/pics/img{01..10}.jpg does re-use the
connection (when it is possible); in other words, in the best case, you
have one process and one connection.

We do, when it makes sense.

People use GNU/Linux.

Still you haven't explained why

  wget -batch "http://rahulprasad.com/pics/{1..5}/img{01..10}.jpg";

is clearer than:

  wget http://rahulprasad.com/pics/{1..5}/img{01..10}.jpg

and why "non-technical" people needs less time to learn the first
version.
