That's complex. I wouldn't be inclined to let you change the start of an active partition.
Changing the _finish_, however, shouldn't be too much of a problem. You leave it up to the user to make sure they resize the filesystem appropriately. So there's no extra code in the kernel. Just one fewer check for the ioctl.
