by "such restrictions" I was referring to the devices reinoud had mentioned,
things like CD-RW where rewriting a sector is not as simple as just writing
it again. for normally-rewritable things like floppies that just have a
sector size smaller than 512 bytes, we can work around the interface limitation
if anyone really wants to. but I just don't see it being worthwhile to
change the device strategy interface for such obscure devices at this point.
