Yes, that note was me adding something to my todo list. :-)

By "user OOB bytes" I meant things other than the ECC and the bad-block
marker -- the space described by oobavail in ecclayout. This is getting
less useful with partial-page restrictions and large ECC that fills up
most of the OOB, though, and thus there's a trend away from making use
of it. So if it's a pain to provide access to any spare OOB bytes, it's
not that big of a deal.
