Some of you may hear me ramble about how Mishustin is now canon, but not understand how he is canon. This explains his canonness.
Mikhail Mishustin himself is not canon.
There now exists a canon lore character named Maxim Mishustov.
Mishustov is chairman of the Bureau of General Affairs for the Third Soviet Union. In other words, he leads it.
The TSU stole the Vago, well, its remains.
That’s about it. At least thats how I understand it.
