reset: silent for some commands, verbose for others?

Looking at the reset's command third form:

  reset [--soft | --mixed | --hard | --merge | --keep] [-q] [<commit>]

* --soft, --merge, --keep are silent.
* --mixed prints "Unstaged changes after reset: ..."
* --hard prints "HAED is now at..."

If all of those commands move HEAD, shouldn't all of them print "HEAD is
now at..."?

Why should only --mixed print the list of unstaged files? e.g. Isn't it
useful for --soft to give a list of "Staged changes"?
