Per the design.  "C-h k RET" displays this text:

  RET (translated from <return>) runs the command newline, which is an
  interactive compiled Lisp function in `simple.el'.

  It is bound to RET.

  (newline &optional ARG INTERACTIVE)

  Insert a newline, and move to left margin of the new line if it's blank.
