I've talked to upstream briefly, and they seem to be interested, but it's not something that's coming immediately. Note that there are lots of limitations in the current implementation that are probably non-trivial to get around: - Only growing is supporting, not shrinking. - You can only grow your file system to a set limit -- the limit is found by taking your current size and rounding up to the nearest N MB; N is 256MB for 1kB blocks and 16GB for 4k blocks. (You can use the ext2prepare tool to get around some of these limits, but then you need to take the filesystem offline anyhow.) - There are other odd limits, such as “you can't upgrade a file system <23GB to >45GB online, ever”.
