I can empathize, but am also wondering if some of these are feature requests in disguise. For “how to call api” docs, sample code, and even client libraries can be generated from your OpenAPI specs. Link to the docs in every reply. The more complex asks could be translated “build this endpoint and charge me for it”. If all else fails, set up partnership with devs who want to fix/build customers crap and figure out some copy to direct the more complex asks to them.
Agreed, client libs and sample applications have fallen by the wayside and could provide a solution here. It makes it very obvious to the customer when they download and run something that works, and then their changes break it, that the issue is with their changes.
