Description (last modified by saraedum)

Currently this does not work:

sage: CyclotomicField(5).maximal_order().coerce_map_from(ZZ).is_injective()

This probably works if we switch over a DefaultCoerceMap_unique to have the right category set, i.e., with #23184.

Is this still relevant?

sage: CyclotomicField(5).maximal_order().coerce_map_from(ZZ).is_injective()
