ext2 - ext3 - ext4

When ext3 arrived, it was basically an ext2 with journalling. You didn't
have to bother, just mount it as ext3 and you are done. If you didn't like
it (who didn't?), you could just remount it as ext2 again.
The new code sounds similar - just mount it and you have nicer features.
The downside is: once mounted as the new type, you can't go back to ext3
anymore. So it *must* be called ext4, or at least not ext3. It's
incompatible (not much, but still), so it can't have the same name!
