It also seems like ext3 disappeared. The Linux model is that the current incarnation of the ext2/3/4 driver is named "ext4," and that's what Linux users expect. You can mount any ext2/3/4 filesystem with the Linux ext4 driver. For ext4, it was a result of wanting to keep ext3 stable while developing ext4 in-tree. (For a while, it was called "ext4dev"). ext4 is long-since stabilized and ext3 became fully redundant with ext4, so I guess they dropped it. I think we should just follow that convention and rename ext2fs to ext4fs. We can mention support for the less-used ancient ext2/3 in a COMPATIBILITY section or something, if we don't already, but ext4 has been the go-to basic Linux filesystem for a decade. (Seriously: "On 11 October 2008, the patches that mark ext4 as stable code were merged in the Linux 2.6.28.") If we support ext4, call it ext4. My 2ยข, Conradhelp
