On the other hand defining commands using a special command or via redis.conf would be a problem for a few reasons:

Different instances may have different versions of a command implementation.
Deployment is hard if there is to make sure all the instances contain a given command, especially in a distributed environment.
Reading an application code the full semantic could not be clear since the application would call commands defined server side.

In order to avoid the above three problems and at the same time don't incur in the bandwidth penalty, Redis implements the EVALSHA command.
