Current use and fit
Most clearly implemented by Mudlet; any GMCP-capable engine can add it without another Telnet parser.
Implementation essentials
- Negotiate GMCP first, then advertise only the Client.Media version implemented.
- Use HTTPS, bounded downloads, stable cache identifiers, and explicit media types.
Compatibility and safety notes
- Remote media remains an active-content boundary.
- Do not override client media preferences.
