It's not irrelevant, since a person doing that rewrite will be
conscience of whitespace during the re-write ..

The same with general coding style, if someone does a rewrite who has
been alerted to checkpatch problems they will likely use it themselves
leaving no need for someone else to comment on it.

There's plenty of large projects that never get off the ground cause
people don't follow the coding style, or don't write clean code.. Take a
look at the staging tree there's plenty of large dirty projects in
there.
