I think naked kwargs can be abused, but there are many legitimate use cases for them. For example, we interface with a message bus that uses JSON for transport. There are several different ways to enqueue a message onto the bus, and it would add a ton of complexity and no real value to define the parameters for each of those Send APIs.

Looking at it another way, the hunk of code in charge of serializing your message does not care one whit about the innards of each message, and making it become aware would add tremendous complexity with no real value.
