What this server is known to support, decided without asking it.

Every query here is local: the implementation and backend were established once, and answering from them costs no process and cannot fail.

## Members

- `implementation` (attribute)
- `backend` (attribute)
- `supports` (method): Purely local: this never launches tmux or touches a server.
- `refuses` (method): Whether this implementation is known to get the feature wrong, which is the opposite question from `supports` rather than its negation.
