I strongly agree with this description of the limits of zone cuts.
"nom.fr" (nom == name in French) is a different zone (RFC-2181
speaking) from "fr" but they are managed by the same entity and obey

Zone cuts exist for the convenience of DNS administrators. It's

it's not unheard of to combine multiple administrative domains into
a single zone if they happen to be hosted on the same DNS server.
Less frequent, IMHO, and a bad idea.
