The problem - except that Poland is always happy about to be a problem for Germany - is in a totally other way. First problem: Germany needs the own weapons - specially also on reasons of our duties for the NATO-shield. Second: Our best weapon systems need a lot of know how and a long vocational training in theory and practise. Third: The Ukrainians needed very fast weapons - and much more important: They need also the whole spectrum around weapons: logistics, training, amunition, repair parts and so on and so on. That's why we had the idea of a so called "ring-exchange". Some nations gave weapons to the Ukraine they are easily are able to use and which we replaced and/or will replace adequate with German and/or NATO weapons.
If I am right then this what the stupid and criminal Polish government calls "junk" is one of the most effective weapons - more modern than antiquated - which are used from Ukrainians who got a shortened training. Under constant fire without optimal service it may happen that such a weapon has to be repaired. And in general are also older weapons which are reactivated not "junk". This is comparable with aeroplanes who are always "young" or "new" as long as every part is replaced before it will reach its limits of use. Whatever will happen with whatever German system of weapons - I hope the Ukrainians will directly inform our government and/or our army - or our newpapers if no one of them reacts. For sure the Ukraine not needs a Polish guardian if "the Ukraine" - whoever this is - likes to tell us something.
