Should we support basic types for ChannelKinds?

[dhylands]

For example, I need a String getter/setter to get/set the camera_name, username, and password, and it seems kind of lame that I need to create Extensions to do this.

Perhaps we can have a simple extension kind that is just a JSON object?
Why do we need a vendor for custom kinds and not for OnOff?

If you don't mind, could you move that discussion to fxbox/deprecated-taxonomy#72? Unless I'm missing something, that doesn't really seem sound like RFC fodder to me.

As mentioned over there, ChannelKind is not about types but about feature discovery. As neither String nor JSON is a feature, neither fits in ChannelKind. I don't see why you would create an Extension rather than a new variant, though. Since Name, Username and Password are pretty generic features, they would definitely fit in ChannelKind (at least until we adopt a plan for #8 and get rid of ChannelKind entirely).

Regarding vendor: it's the name of whoever came up with the extension. Basically, it's a namespace, to avoid mismatches between two extensions with the same name.
