Due to https://github.com/rackerlabs/otter/pull/405/files#diff-1bed9efd41b5b5053bae065c1dda62d5R721 - I use the function to build the list of webhooks from the data from cassandra, and if I don't include the ID, I'd have to then manually insert the data (2 list comprehensions instead of one, or an extra inner function) - which maybe is better anyway?   I was originally going to just always include the ID, but that involves changing a lot more code (the CQL for fetching a single webhook does not get the ID, for example)
