Each of the ext-tags alone is not that much frequented currently. We have: ext2 (x5), ext3 (x2) and ext4 (x8).
Shouldn't we merge them together into a new extfs, and convert the 3 old ones into synonyms? Or do they really make sense stand-alone?
I don't think so. They're certainly related, but an "ext4" solution will not apply to "ext2" and vice-versa.
It just doesn't "feel" right to me.
