Though a cynic might wonder how long Germany would be satisfied with them, once the Russian army had melted away and gone home, as it presumably will once the shooting stops.
Incidentally, what was the Ukrainians' attitude to the PG? Are they still likely to declare independence at some point?
The Ukrainian Rada was so hostile to the PG that it tacitly supported the Bolshevik coup. (This is something which neither the Bolsheviks nor the Ukrainians liked to talk about later on!) Still, until the country was overrun by Red troops in early 1918, the official position of the Rada and its General Secretariat was in favor of federation, not complete independence.
As late as November 1917, after the Bolshevik coup, the General Secretariat had vigorously denied any striving for independence from Russia:
"All rumors and discussions about separatism, about the separation of the Ukraine from Russia are either counterrevolutionary propaganda or a result of simple ignorance. The Central Rada and the General Secretariat have announced firmly and clearly that the Ukraine is to be a part of a federal Russian republic, as an equal governmental entity. The present political situation does not alter this decision one bit."
