I couldn't believe this didn't already exist.

There is shell-command-on-region and shell-command-as-string, but
nothing that combines the input marshalling and the output marshalling.

You mean, just like C-u M-| ?

No:

  M-| runs the command shell-command-on-region, which is an interactive
  compiled Lisp function in `simple.el'.

  It is bound to M-|, <menu-bar> <tools> <shell-on-region>.

  (shell-command-on-region START END COMMAND &optional OUTPUT-BUFFER
  REPLACE ERROR-BUFFER DISPLAY-ERROR-BUFFER)

  Execute string COMMAND in inferior shell with region as input.
  Normally display output (if any) in temp buffer `*Shell Command
  Output*';
  Prefix arg means replace the region with it.  Return the exit code of
  COMMAND.

1. I need the output _as a string_.  Not in some " *itz-temp-buffer*" which
I then have to messily kill.

2. I need to pass the region to the program _as stdin_.

and also

3. I need to avoid the interactive side-effects of
shell-command-on-region, such as its tendency to create a new window to
view the output buffer.

Of course.  Elisp code rarely if ever needs/wants to call things like
shell-command-on-region.  It should use call-process and friends.
