Actually, slightly tangential to the topic, but I wonder how many DDs are actively working on
the lower-level stuff. I do not believe it is an insignificant figure. For LWN's kernel
contributor analysis, redhat shows up because the contributors are using their @redhat.com
addresses. It would be nice to see some people use their @debian.org ones and see if Debian
could get into the charts. However I expect DDs who are employed to work on kernels are using
their employer's address for commits.
