Comment (by ajfleming):

 This post by Ryan McCue; [https://journal.rmccue.io/351/the-complex-state-
 of-meta-in-the-wordpress-rest-api/ The (Complex) State of Meta in the
 WordPress REST API] explains why complex values & serialized data are not
 exposed by `register_meta()`.

 > The key reason for this is that accepting serialized data is either
 lossy or unsafe.
