Hi Markus and all,
My instinct is that it's better to just make sure it's easy to find the current
ordering on a queryset. I suspect the use-case for modifications is not super
common, and I'd rather not bother with specifying the exact behavior of
nonsense cases like order_by(None, append=True) and
order_by('?', prepend=True) -- which, as the framework, we'd be required to
do, but if you're modifying a list on your own, you're free to ignore.
My 2 cents,
Shai.
