Warning: alpha software intended for developers only!
The question is somewhat related to creating a Version 3 of the Ethereum wallet format file
Does this goes to
Since there is no truly "official" software to begin with, I'd say that any technical questions relating directly to tools for Ethereum are within scope. Just because a tool is in alpha, doesn't mean that it should be out of scope, either. This question is more about how to generate a Ethereum wallet file than it is about a particular wallet anyway.
If we start drawing arbitrary bounds around what is or is not 3rd party software, it could lead to difficult decisions in the future. Are technical issues interacting with DApps off topic? What about issues with "3rd party" clients like Parity?
The network is owned, run and monitored by everyone, but controlled by anyone.
Therefore, everything is third party software. There is nothing official by definition. Of course, there are reference clients, but they are just technical examples of the yellow paper definition.
I clearly see no reason why anything should be out of scope of our site if it's related to Ethereum, its blockchain, smart contracts, decentralized applications, including the Swarm and Whisper protocols.
