I guess the question which arises is whether you have ever seen a similar setup in new construction or an inspected renovation. The AHJ would have the final say on the matter.
When I find 'em, I do a good job of pointing it out to the Client that there is no overflow. I see this with ultra high-end fixtures, such as ceramic bowl sinks in wooden tables. These fixtures are really expensive and are made to look loke something you'd see in a western hotel in the 1800s. No overflow on them, either. The other question you have to ask yourself is with the sheer volume of the cultured marble sinks sold in every home center in the US, do you think they wouldn't comply with a code requirement? Hmmm...
