Also, wasn't Aurora Serverless created because of that problem?

I think Aurora Serverless has even worse [1] cold-start times (for the DB itself), and it was intended as more of a price-optimization than a performance boost.

Aurora Serverless also handles connections. The problem of having a burst of 1000 concurrent invocations accessing your databases still exists even with VPC access

That limit can be raised, apparently. I've seen mention of limits up to 30K concurrent invocations.
