I've tried to implement REST to its exact specifications before, turns out less common verbs like DELETE isn't implemented the same way across platforms and libraries because the IETF never specified. This means no standardization regarding having variables in the path vs the body vs headers, with some libraries or even OS level recognition preventing that, while the server may be looking for it

this incongruence pushes people back to using just GET and POST methods in flexible and overloaded ways

Agentic engineering knows all the best practices and ways to get around these limitations in the most compatible way and cranks out full APIs with all the verbs
