Not really. But it's mostly because the support for other features is basically non-existant. It also seems like all development is happening on Aurora Serverless v2 (which I think is in preview state?). The scaling also isn't seamless, it breaks your connections if you're using prepared statements - we have it pinned to a specific number of capacity units. We'll probably move to plain Aurora at some point, as that supports all bells and whistles, but for now Aurora Serverless is good enough.
