When I receive patches from such series, I often assume (and often incorrectly 
it seems after reading this thread) that the submitter will want to merge the 
whole series through a single tree. I try to always ask when sending my ack 
whether I should take the patch in my tree or if it will be merged through 
another tree. This wastes bandwidth, and would be pretty painful for you if 
you had to tell 200 times maintainers to take the patches. I think documenting 
the expected default upstream path for tree-wide changes would help here.
