No, there are people out there who are not ffmpeg devs who do debug
filter chains and know what they are doing and taking away the docs
would hurt them plus new developers who try to find their way around.
I'd prefer trying to make it clear in the text what they are for and
then live with the remaining misunderstandings. Just my 2c.
