I think a lot of people missed the discussions behind the API since we
did them basically behind closed doors. The main focus will always be
the client application. You really have to think the other way around.

And the weird indentifiers are free formed strings that doesn't match
any of the other categories. And since the server will hand them out it
is an easy requirement to fulfill. These are also not meant to have any
meaning. In general they can be random garbage. The server knows what to
do with them.

You will also see that we love using strings, because in languages like
Python they are so easy to handle. If it is not an integer by definition
we might go with a string as type, because it is more flexible.
