I think that we know this problem exists, but I'm not aware anyone is
working on fixing it. There is a "Merge Append" patch floating around
out there that I think might help with this, but AFAICS it was last
updated on July 5, 2009, and still needed some more work at that time.

Since this is an all-volunteer effort, complicated problems like this
don't always get fixed as fast as we'd like; most of us have to spend
most of our time on whatever it is that our employer pays us to do.
Of course if you're in a position to sponsor a developer there are a
number of companies that will be happy to work with you.
