It's more complicated than that.

You might be perfectly okay with having certain systems shut down, but you probably still want to pay for the archival storage of your important files.

That archival storage might be in several places, including one S3 bucket, whereas there might be another one that, contains copies of scraped Craigslist for X where you'd actually be happy that it just shut down.

This makes it far more complicated to do correctly, and as others pointed out, mostly relevant for hobbyist — this is not something you are going to make a lot of money from.

Better to spend engineering hours making an MCP for the dashboard or improving your Databricks setup.
