Up to you.  Keep in mind that I give comments that make sense by looking
at the individual patches, without much context of what's coming after.
For a change of this size, it would be too difficult for me to make
comments considering the patchset as a whole, it just wouldn't fit in my
head.  So if some code gets removed down the road and doing the change
isn't really useful, it's ok to say that and ignore the comment.
