This is a vast oversimplification. Even if you give your customers what
they want, you can still be wrong if your solution fails to behave
properly in relation to the rest of the world (stealing resources,
violating other people's rights, etc).
Once upon a time, telephone industry listened to its
customers (telephone companies) and provided them with what
ehy want.
As a result, telephone equipments becaome more and more
complicated with more and more complicated specifications.
Most of them are overtook by simpler equipments using IP.
The world is complex, sometimes solutions must also be complex. In those
cases the design choice is where you put the complexity.
This, however, is right on target.
In theory, maybe.
However, I have never seen such a design choice necessary
for network protocols.
We don't need 3GPP for the mobile internetworking.
