Developer time is the highest cost. Building and deploying a function in an hour minimizes time to market and opportunity cost. Lifting and shifting to a dedicated service like AppEngine is a "good problem to have" once the function's usage exceeded specific thresholds. However, if you never reach said thresholds (e.g. only a few thousand calls a day), you didn't spend the time/money setting up a service backed by dedicated services.
