Seems fair enough to me -- if the wget output is actually needed at some point in the future, one can always get hold of the sed incantation from git. That being the case, a warning could be added to the modified wget404 to say that it now discards output, and that if that's a problem one should look at <relevant commit> for a version that manages to preserve it, as long as /dev/fd/4 is available. The fact that /dev/fd/4 is missing does seem to be a separate bug, but a quick grep -lr suggests that this is the only place it's used in d-i, so perhaps a bug we need not worry about too much.
