Think of them as being special devices with constraints on them. Like character devices for cartridge tape drives on other *ixes, which can only read multiples of 512 bytes at multiple-of-512-byte offsets because that's all the tape drive itself will do. (Not applicable to Linux because Linux uses block devices and reblocks the I/O in the kernel... which has its own drawbacks.)
