Might make sense to omit the tags on the MAINTAINER-source. I can
agree to your reasoning there. 


As far as I can see, the use and the use cases for the git-part of
get_maintainer.pl are mostly to get patches to not-so-well-maintained
parts of the tree upstream. What I envision for the git part is a
scoring based classification scheme that uses all readily available
information of the git-history to determine relevant people for patch
review and patch routing.

I already have implemented a small parser that extracts that information
out of git-log and makes them available to the script, but didn't have
time to wire it up yet. 

Another improvement (beyond finding a decent heuristic based on the
artifacts 'authorship', 'signed-off-by', 'reviewed-by', 'acked-by',
'committer' and nr-of-lines-changed.. and maybe time) is probably to
not make an arbitrarily 1-Year-Back cut-off, but to check the last N
commits on that region of the tree. (I'm thinking of the more
"settled down" areas of the tree here)
But let's see what I come up with...
