As the years go by the code diverges and it becomes much more
difficult to merge. Because of the code divergence the signal to
noice ratio in the commit mailing lists (the number of commits that
are relevant vs. the ones that are not) decreases. The number of
people who are know enough to be able to read, undestand, and pick
the good information from both code bases also is also dropping.
