Neither have I.
(The following is mainly opinion - no actual facts!)
I've seen conflicting information on t'net as to whether all channels available over-the-air on Freeview are available ota on Freely. If they are then there is a possibility that all current channels could be recorded. I suppose trick play (eg. skip) might be disabled. Who knows.
It is highly unlikely that the new box would record from the internet. If it did your recordings could be time limited and copying to another device prevented. You may need the internet to verify your credentials for a recording and for seeing adverts Skip to avoid them -

no chance!
