We're going to need default hard budget caps on pretty much everything

Coding agents and pay-by-usage APIs are pushing the need for default hard budget caps that stop services with errors once monthly spend limits are hit instead of only sending warnings. AWS launched spending limits in a new experience on 16th September, pausing a project for the month when usage reaches the spend limit. Providers should make hard caps the default and move optional removal behind a clear opt-in so users avoid surprise large bills.
