I thought that additionally it was to help scripts (svnmerge.py as the
prime target) which redirect all output to be invisible to the user,
to prevent the client from asking for input (and thus dead-lock
waiting for user input).
For svnmerge.py, I believe the --non-interactive option wasn't an
option because it's feeding input into the client on certain types of
information requests.
svnmerge.py got broken by 'svn merge' becoming interactive 'all of a
sudden' as well as 'svn cp' requiring server contact (before we
eliminated that again.
Just to add to the list of reasons why it happened. No judgement.

Erik.
