Since the technology is based on knative, it should in theory be possible to run these on a local k8s instance. It would support some debugging use cases.

I do agree as far as cold starts and runaway expenses go, although those issues seem inherent with FaaS.

The biggest issue isn’t being able to run locally, it’s getting access to systems where an unexpected error is happening in production that didn’t happen in dev.

For expenses, it would be nice if there was a way to automatically shut off or throttle traffic after $X a month.
