Why 'get' unsubscribes from a dataref?

[cosmolabs-ru]

Thanks a lot for adding 'get' command, it's very useful. But why does it unsubcribe from a dateref? What's the purpose of such behavior? Can I safely use 'sub' repeatedly to periodically fetch values of already subscribed datarefs? Is there any other way to fetch a value by an incoming TCP request?

Idea of get is that you can get the value once without subscribing to the dataref. There are some corner cases you might want to do that. If you want repeated updates, you subscribe to the dataref normally. I don't understand any problem with this.
