I would use them much if they were available.  Non-interactive editing
is really useful in some occations, like non-interactive package
install (configuration file modification), and simple text
substitution of many files.  I use /bin/ed for such purposes now.

(It's suprising that the "cp-and-sed" technology is used for the
 latter purpose above in Pkgsrc which I believe the most engeneered
 part of NetBSD.)
