   the previous protocol may break the context migration, or (even
   worse) yield an incorrect context after migration.

   If you change this encoding compared to `Constants_parametric_previous_repr.t`,
   you should ensure that there is a proper migration of the constants
   during context migration. See: `Raw_context.prepare_first_block` *)
