Primarily because index AMs and opclasses can only be defined by
superusers, and the superuser is assumed to know what she's doing.
More generally, we've never made any provisions for the properties
of index AMs or opclasses to change on-the-fly. I doubt that doing
so could possibly be justified on a cost-benefit basis.
