Let me explain this a little further.
Motorola learned, that sparing one address line was not worth the 
hussle that was not necessary on other architectures, so later on 
they added the missing line (in 60030). If now a language exists, 
that make good use of direct bit-addressing, some time later they 
may also be available in hardware, so the alignment requirement 
can be removed also.
Segmentation may be a good idea if every line in hardware is 
extra ordinary expensive, but nowadays it should be no factor 
anymore. It's only a traditional bad habit to segment the memory 
into bytes.
