Comment:

 This sounds like PHP limitation, maybe check
 https://www.php.net/manual/en/language.oop5.serialization.php.

 Think this is a documentation problem in WP. Imho the docblocks for adding
 options and meta should state clearly that saving instances of PHP objects
 to the DB is not recommended and that only simple objects are supported
 (like plain name->value pairs?). Also that the preferable format to save
 to the DB are strings or associative arrays, not objects.

 Setting this as a "documentation enhancement" for 6.5.
