There seems to be no clear consensus that would satisfy lawyers (track
complete copyright information) and practical point of view (it's in the
git metadata). The problem not only I see taking this patch as an
example is that your (c) name now appears in file containing changes
from several other people whose names are not mentioned (but yes the
original copyright is preserved).

I don't want to speculate what would this mean from the legal POV and I
think we've heard each other's arguments. If there's a recommended
practice coming "from above" as linux project, like it was with the
SPDX, ok let everybody add their copyright notices. But until then I
won't take such patches.
