Yes, I think they would be. That being said, copyright notices in the
Linux kernel are horribly out of date/inaccurate and even Git does not
do a good job of recording these (garbage in, garbage out). Git only has
a single "Author" field and I know of commits where the commit message
had two authors listed and the that was added had three authors listed.
Then there are all kinds of silly tags in the Linux kernel where it is
absolutely unclear whether or not someone is claiming copyright or not.
See for examples this article:
https://www.ifosslr.org/index.php/ifosslr/article/view/121

Also, author doesn't necessarily mean copyright owner, company
affiliation also does not necessarily mean copyright is with the company
(it depends on the work contract) and it would require a lot more
research to find the true copyright owner.

The copyright statements also have other relevant information, such as
years. This is relevant to find out which copyright laws were in effect
when the code was published.


> Or should we introduce an SPDX header for that ?


There was a discussion about this a few days ago (please see the list
archive). Personally I don't see the benefit.
