Yes, but this would also break any application that uses READ_BLOCK or
WRITE_BLOCK, as well as requiring changes to the basic ProDOS command
structure (since a file with the same number of blocks is now capable of
having more data in it).  In other words, it would probably break about 55%
of the existing ProDOS 8 programs available today.
