Just as an aside, we just upgraded in place a large number of ext2
file systems to ext4. The process completed very smoothly and created
a performance boost for almost every workload we had.

I think keeping ext3 around is really convenient to compare against
ext4 as it becomes more mature, but outside of its academic use I
don't see any good reason to keep it around. With such an easy
migration path for users (mount as ext4 in place) I think an "end of
life" plan should not be that complicated and encouraged.
