Comment (by vdelecroix):
We do have
{{{
sage: K.<a> = NumberField(x^3 - 7, embedding=AA(7)**(1/3))
sage: AA.has_coerce_map_from(K)
True
sage: K.<a> = NumberField(x^3 - 7, embedding=QQbar(7)**(1/3) *
QQbar.zeta(3))
sage: QQbar.has_coerce_map_from(K)
True
}}}
Isn't it enough? What should be simplified is to automatized the embedding
into `AA`/`QQbar`. And it is more or less the purpose of #19356.
