Relatively hard to get right. You have to deploy a ship (maybe merchant ship) and a specialized crew to the actual location, undetected, at the right time. A lot can go wrong.
I suppose Austria, Hungary, Romania, Czechia, et al do not have the resources to pull this off. Remember, it's only been a couple of months that this gas stand-off is this tense. The only countries in Europe who have the means to act fast on this are the UK, France, Italy, Spain, maybe Greece (I don't think any of them would do it - there's no reason for it whatsoever), and Poland.
