Oh sure, it's a trifle.

The whole concept of lines +/- is kind of dubious.
Quantity really doesn't judge value.

It makes some sense for patches where new files
are added, but new files are a relatively a small
percentage of the overall kernel source tree.

Let it stew for awhile in Andrew's tree and when
-next opens up again, let's see if there are any
other comments about it.

My guess is very few people will notice.

The best mechanism is to have MAINTAINERS entries.
