I wouldn't be opposed to a 195 division, but it would be too shallow since it would probably pull a lot of people from 205, which isn't that stacked. It may also pull a few from 185, but its more likely that some guys would drop down.
The attraction with HW is the large weight disparity, so its a special case. Weight also matters less as much once you reach a certain point, like 225 lbs+, because the skill is far lower at HW. It gives everyone a chance to be competitive. Example: You're not going to find a natural 145 lbser who can beat a natural 170 lbser because both divisions have a high skill level. But there are plenty of 230 lbsers who could beat 265 lbsers at HW.
