Review comment:
If we have something like:
```java
public interface User {
...
@Deprecated
default List<? extends ActivityRecord> getHistory() throws
GuacamoleException {
return Collections.emptyList();
}
ActivityRecordSet<ActivityRecord> getUserHistory() throws
GuacamoleException {
return new SomeSortOfSimpleActivityRecordSet<>(getHistory());
}
...
}
```
Then we end up with:
| Extension implements... | Result |
| -------------- | ------ |
| Only `getHistory()` (older extension) | Webapp invokes `getUserHistory()`
which calls `getHistory()` by default and works as expected. |
| Only `getUserHistory()` (newer extension) | Webapp invokes
`getUserHistory()` which works as expected. If an older extension decorates
`User` objects and attempts to do something with `getHistory()`, it will not
have any effect and may behave as if history is unimplemented. |
| Both (masochistic extension) | All calls to history-related functions work
as expected. |
| Neither | Calls to either `getUserHistory()` or `getHistory()` have the
same result: empty set of records |
That seems OK except for the case of inter-extension calling of the older
`getHistory()` function.
