/**
 * Changes as compared to upstream:
 *  - markdown is preferred over plaintext
 *  - informative members are public and others are protected, not private
 *  - onServerInitialized() was extracted; it also emits a message once connected
 *  - initializeParams() was extracted, and can be modified by subclasses
 *  - typescript 3.7 was adopted to clean up deep references
