The Treaties haven't changed since 2011 or so, and I don't expect any changes in the next decade at the very least.

Agreed, no big changes imminent. I was thinking more about the longer term. I would expect change in 20 or 30 years, and a lot of things could happen to change things even in the next decade (another financial crisis like 2008, another pandemic, wars, etc.).
