As far as people who want to use ext3 as the beginning point
to do something that is has no forwards- compatibility, there's
nothing stopping them from creating a jgarzikfs if they want. But I
think I can speak for most of the ext3 development community that we
feel that one of the strengths of ext2/3 is its ability to do smooth
upgrades (and in many cases, downgrades as well, when people need to
migrate a filesystem so it can be mounted on older kernels), and that
it's one of the reasons why ext3 has been more succesful, than say,
JFS.
When did I ever say smooth upgrades were a bad idea?
The whole point of 'cp -a ext3 ext4' is to ensure smooth upgrades
continue. A key theme is to avoid -backporting- all this new stuff
that's going into ext4. IMO ext3 shouldn't be a devel platform at this
point in its lifecycle.
