I wondered about the same. In general I would expect all of this be
handled by one set of tools. Similar like we handle UFS and UFS2.
 
I did not check myself but it seems the Internet thinks that dragonflybsd
has ext2/3/4 support all backed into the ext2fs implementation which is
probably close to ours. If that is true there may be a place where a lot
of the code can be picked up.
