I am not sure what you see as penalty here.

I think two factors made the original size decisions sensible back then:

 - for large disks the space lost to alignment does not matter
 - native block sizes > 512 byte only happened for larger disks initially

Overall it would be better to enforce alignment as least as large as the
native block size on *any* disk - but IIRC it is quite hard to find that
value in all cases.
