I'm writing a Ktor plugin capable of sending an HTTP response when catching a specific exception. The response body is a serializable class.

Should I serialize the class within the plugin code, using kotlinx.serialization?
Which means I would write something like call.respond(Json.encodeToString(bodyClass)).
However the user has no way to choose another format like XML.

Or should I encourage my users to configure the Content Negotiation plugin to serialize the class?
Then I would write something like call.respond(bodyClass) and serialization will be automatically handled.
However, this code will fail if the Content Negociation plugin isn't configured.

I would encourage users to install the ContentNegotiation plugin to evade implementing serialization configuration.

That’s what I was leaning to, thanks!
