Good analogy. Maybe a concrete example from my own recent usage would also show
some of the utility of this feature...
The default position of the vignetting module near the end of the pipe is good
for "effects", ranging from "moody insta-filter" to an opaque, sharply defined
oval framing of the image. It's *not* good for realistically simulating actual
lens vignetting. However, if you move this module to an earlier position, just
after the cropping module... suddenly it does a very good job of this. If you
move it to just before the cropping module, it can even do a not-terrible job
of *compensating* actual lens vignetting. I have infinitely more use for both
of these functions than the "effect" ones, and always use this module moved
from its default location.

It's a very useful feature, it's not rocket science, but it does require some
common sense and a basic understanding of processing order (the kind that most
people who have used layer-oriented image editing software already have)... and
there's absolutely no *requirement* to mess with it - the default ordering is
still as good as it ever was (actually a little better, in fact).
That said, I personally don't think that making a user change a default
preference or perform some other basic "yes I RTFM" operation before the
feature is exposed would be a bad thing.
