This and kernel compression are the two pieces that worry me a little. LZO is still probably one of the best speed/size compromises and was the reason it was added to jffs2. I'm not sure there are many devices that still use flash directly via jffs2 but this probably still does have a use there. Obviously it would still be in meta-oe but I'm worried the "off by default" will catch out a few old BSPs and be a pain to enable. At lot of this history was paged out in long term storage!
