In the United States, we do have the excepted foreign state concept, where certain investors with very tight ties to Five Eyes countries aren't subject to the non-controlling jurisdiction. All countries are still subject to the controlling jurisdiction. When you have mandatory filings, to the extent that you can focus on higher-risk transactions, I think that's the right approach.
I would be reticent to wholesale give up jurisdiction over control for all countries, because one of the things CFIUS is also looking at is third party ties. Perhaps a company comes from a jurisdiction that's not of concern but has extensive ties, for example, to a foreign government. That's something CFIUS could consider. Again, this is some balancing and line drawing.
