I'm not sure this leak is all the significant. The swiss leak think came with a lot of banking data, which is far more useful than this. This only proved what everyone knew, certain jurisdictions attract a lot of people wanting quick incorporation with good secrecy. This doesn't prove wrongdoing by the people listed and even if does, they are likely to be fined for not having disclosed shares of this or that company. There is very little incriminating financial data on this, its the banks that have that data and their data was not leaked
