Keep or scrap Romanian units

[Weasel]

I am at the point now that my army is so massive that I have to downsize.  German units are feeble at best except in Hungary where they are putting their best units, not sure why.  Anyway, I am not at -750K troops even though I have disbanded over 200 units (construction, artillery, some divisions).  A large source of troops I can get rid of is the Romanian and the Polish once they are unfrozen, I know Romanian is the only army that can enter Hungary but they are so weak who cares.  Are they worth keeping, along with the Poles, or should I disband them? In other words, do they hold some hidden purpose for late in the game?
