Rather than keep the old ones around, I would just change the
implementation of the API methods to one which does something like:
```java
return Tables.getNameToIdMap().entrySet().stream()
.collect(Collectors.toMap(Map.Entry::getKey,
e -> e.canonicalId(),
(v1,v2) ->{ throw new
RuntimeException(String.format("Duplicate key for values %s and %s", v1, v2));},
TreeMap::new)));
```
