It is used. :)
nand.h
#define NAND_CANAUTOINCR(chip) (!(chip->options & NAND_NO_AUTOINCR))

Yes, most of the 1st generation chips (256/512 byte pagesize) have this
feature. It's important to be aware of this.
After reading a page, those chips are automatically transferring the
next page into the read buffer.
The 2nd generation chips (2K pagesize and a couple of the newer 512byte
pagesize chips) do not have this feature, so you must explicitely issue
a new page read command to get the next page data.
