Yes, but it wasn't given, verbal insults were proclamated and ATO was started, they seem to be deadly angry. If they feel they're victorious or if they start to feel strong support from Mother Russia (like now?), they might wish for more. Besides, they might be saying one thing and wishing for another. And at first they had different moods between them.
I mean, now they can even aim for ZNR (Zaporozhye), though I have no idea how can Zaporozhye be a part of "Novorossia". And basically if we show that after serious agression we give up land and EU does nothing - then any other land can be taken from us. And since it won't be done without war, this would lead to thousands of casualities.
tl;dr no matter what happens from now on, there will be suffering.
