Constants in the AOT snapshots are used for canonicalization of the instances, which in AOT will be limited to canonicalization of cross-isolate_group messages. Such messages are only limited to instances of core classes, it is not allowed to send user-defined instancess across isolate group boundary. So constants created for user-defined classes won't be used, can be eliminated from the snapshot.
