I don't see why allowing an output URI to be the same as an input URI should
have to change the simple rule that source trees cannot change (or be
writable). In practice, the result of the transformation could be used to
replace the original file but only after the transformation is complete. I
don't think Bryan was suggesting that side-effects should be allowed. This
shouldn't be an error, IMHO.
