In the scheme of things, DATUM is quite new. Only been around since what, September of last year? Still a baby.

Usually it takes someone who is using a node implementation, who has some dev skill, and who wants to use the application himself to package an app for that platform. It's usually not the devs behind the node implementation itself who take it on.

The less popular the node implementation, the less likely the person with both the skill and the interest in doing the work exists.
