Using the wait-before logic would make sense if there was useful time- consuming work that could be done between the end of one write and the beginning of the next, but it also requires doing the wait-for-ready before reading, because a prior write or erase could still be in progress. Reading is the far more common case, so adding a whole extra bus transaction to check for ready before each read would soak up any small gains that might be had from doing async writes. END
