For sure, the consequences of being required to register are significant. I'm not a leading expert in the area, but generally, the offender is required to register upon conviction, to provide their address and name. If they plan to leave the country, for example, there are all sorts of requirements for what they have to provide. It is very much a tool that impacts the individual. Over time, there have been some challenges to the scope of that, but it's been upheld because of the linkage to the objective, and it's tied to persons that the evidence shows are at a greater risk of reoffending.
The simpliciter offence is, in the way it has been treated to his point, a bit different from the other two offences for bestiality.
