This is the problem with turning your trade agreement into a supra-national prestige project. Conflicting goals.

Economically, it would seem to make sense to turn Hungary loose - there's a lot of investment required before any chance of return.

Politically ... it's fairly clear Hungary is intended to become a debt colony eventually, they just won't comply for now. So the EU will keep hammering away at it until Hungary makes a mistake and gives the EU the opportunity to annex their economy.
