Define 'ultimate responsibility for an implementation'.  I'm further developing
patches that Val has (at least partially) implemented.  By Val's admission some
of the patches she further developed beyond what Jan Blunck had implemented.
The chain may extend further.  To that end all three of us are authors of some
of the patches.

However, if you meant 'maintenance' rather than 'implementation', then, yes,
that would be me (for the moment at least).  But if that's the case, then
shouldn't it be 'Maintainer' and not 'Author'?  And, besides, that's what the
MAINTAINERS file is for.

No.  I would say that properly supporting multiple authors in the commit object
is the cleaner solution.  It's not the *easier* solution, however, and would
require an upgrade to the version of GIT used to parse these commits.  That
I'll grant you.

But if I say to Gitweb "show me the patches authored by Val" it will *not* turn
up these patches, and in that way will deny Val credit.  Yes, you can see that
Val altered that patch if you look at that patch directly - but you have to
know where to go and look, in which case you already know or suspect that Val
is credited with patches in that area.

So to make (2) work, Gitweb needs to search for the additional authoring fields
when asked to credit people with the patches they've worked on.

Similarly gitk and possibly other tools would need to do the same.

*That* would be fine by me, I suppose.  I don't think it's the correct way to
do it, but it might be the logical way since this wasn't build in from the
beginning - and the main thing would be to turn up the prior or joint
authorship to author-based searches.
