It would be great if we would have an Query parameter rewriting policy.
Currently the HTTP URL query parameters added to the API call by the API client are passed on to the Service Implementation as is. It would be great if we could have some influence on this.

For starters it could be used to add generic static query parameters to each service implementation endpoint URL using a policy/plan.

Other possible use cases I can think of:

• Move/Copy a HTTP header to a query parameter.
• Remove query parameter if it exists
• Update a query parameter:
  • Rewrite the value of a query parameter
  • Rename the key of a query parameter
