XML-RPC private?

[Kimbro Staken]

I've seen a number of posts referring to the XML-RPC API as being 
private. That was certainly never the intention when it was originally 
written. The major reason it exists is to give other languages access 
to Xindice, which means it needs to be a publicly documented API. Or 
lacking documentation, it at least needs to be considered OK to develop 
against it if you can figure out how. What's the reason for preferring 
otherwise?
