My take on this is that asking users to keep that zero isn't a
requirement which is hard or unnatural to meet.  On the other hand, I
could envision problems with some future implementation if there are
non-zero bits to ignore.  I don't have a strong opinion.

You're both a "user" and an "implementator", so perhaps you have a
better picture.
