@Tom I also wonder whether we could fix the terminology to avoid confusion, e.g. from the convo with @Nikita Karpuk: • The "extension" -means a single extension point implementation, so a single class name (https://wiremock.org/docs/extending-wiremock/). And extension always means a single class • JAR files may include a number of extensions, and all these extensions will be automatically loaded in WireMock 3. To avoid possible confusion, we could call is a "WireMock plugin"
