Actually, adding a new stream was your idea...
http://lists.gnu.org/archive/html/help-gnu-emacs/2016-06/msg00207.html
I'd never heard of streams in emacs before. I thought it seemed like a
nice idea, so I thought I would give it a go.
Yes, you are probably correct, that append-to-file could be used,
without resorting to new C primitives. However, all the functionality
that we need is already in the C layer. Also append-to-file (or rather
write-region) would need updating to not send messages.
It would also allow fixing this:
(defun append-to-file (start end filename)
(interactive "r\nFAppend to file: ")
(prog1 (write-region start end filename t)
(when save-silently (message nil))))
Append-to-file does not actually save-silently AFAICT, it just hides the
message quickly.
