 * `overrides` answers the different question of what the host actually asked for: the raw fields
 * the providers above this point set, accumulated but never merged with defaults, and `{}` where no
 * provider set anything. A merged value cannot answer that — a host naming the default family is
 * indistinguishable there from a host naming nothing.
