I would like to know whether reasoning can be enabled by default for all queries without needing to set a flag in the request. The reason is that the client I am using does not support additional HTTP parameters, hence the flag cannot be set.
We actually have a workaround for people that can't add HTTP parameters/headers. If you send your query to the endpoint /{db}/query/reasoning then reasoning will be enabled without having to pass in reasoning=true as a query string parameter.
