If lists truly should not be used as domain values in an RDBMS, then we should not allow the domain "string", because the type string is a list of characters; nothing more, nothing less.

Since there are, in fact, no negative consequences of allowing strings as a domain type, I conclude that there are no negative consequences of allowing lists of arbitrary type.
