This has been the accepted way of communicating copyright notices since approximately the dawn of time. The value of the 'author' field within a chain of git commits does not have privileged legal value. If what you were saying is true, it would be impossible for any project to copy code from any other project, unless they did git filter-branch and made sure to follow renames too. As others have noted, it would also be impossible for any patches to be developed collaboratively by different copyright holders, or for maintainers to apply changes. This is accepted community practice and has passed signoffs from a million different lawyers and copyright holders. If you wish to break with this and do something different, the onus is on you to provide the community with _specific_ legal advice; if this is accepted, the development model would have to drastically change in the presence of single pieces of code developed by multiple distinct copyright holders.
