I've not used the product, so it may already do this, but does it ask you for the data it needs in the Pull Request?

I have experience interacting with a logging system, where any diff to the logged data would need a tag like `log_size_increase=3 bytes` – the CICD system would then turn this, with the data already available, into an estimate of the overall extra storage needed.

Perhaps the same could be done. Rather than figuring out "usage" of some serverless systems, which is a very vague question and therefore hard to answer, perhaps it could be more specific. For example, how many requests per second is it expected to receive? Or, which other serverless functions call it (and therefore which will it necessarily have the scale of). Or, what increase in usage would be expected for this change.

It's been a while since I used this tool, but as best I can recall there was a way to provide usage estimates to feed the variable cost calculations. The biggest problem we had was getting development teams to know and care enough to provide accurate numbers. The suggestion in the post below to provide 30 days historical data as a starting point could be a great way to have a meaningful baseline. If someone had better projections, they could provide them, but at least it wouldn't be a total crapshoot.
