No, we did chat in #mtd channel.

Anyway, here's what I think of that. It looks like the idea was to use 
ops.len in order to read more than ooblen bytes, i. e. more than one OOB 
area basically, and preserve ooblen to signal how many bytes there is in 
one oob. However, that seems misleading/redundant since you can always 
figure out how many bytes there are in oob, so it looks like making that 
all work w/ ooblen is better.

Does that make sense?
I'm going to work on that as soon as load permits...
