I agree that one-size-fits-all doesn't work with hardware requirements, but I still think this is a leaky abstraction. The promise of Serverless is not having to care about servers, but this is an option to specifically control that. A better abstraction would auto-optimise hardware spec for the software's performance characteristics - that would be much more "serverless".
