Today, people use reiserfs even though they couldn't just remount their old ext2 as reiserfs. An ext2/ext3-incompatible ext4 isn't a problem. Sure, people will have to mkfs instead of just remounting, and that will mean fewer quick conversions in the short-term. But people using ext3 today don't really need ext4 - they are per definition running on sufficiently small disks/partitions. So an incompatible ext4 will still see use - on new filesystems mostly. Not a problem, people buy disks all the time.
