The field is neither more or less mutable than the original approach.
Strings are mutable too.

FWIW it would be entirely possible, if deemed desirable, to represent
the id as a struct in Go but encode it as a string in mongo,
by implementing bson.Setter and bson.Getter interfaces on the type.
It sounds like that's not necessary though.
