Why is America so hesitant to cut Russia off from the SWIFT banking system?

The only reason I can think of is that cutting Russia off from the SWIFT network would push some countries to adopt a blockchain-based monetary system, which in turn would reduce their reliance on a US-centric international monetary system.

Is this the main fear? Is it the ONLY fear?

Russia has its own Swift alternative SPFS that it could impose on say the BRICs type countries as a condition for buying its oil. In short cutting off Russia from Swift would mean making cutting anyone else from Swift less powerful in future as there would then be a good alternative.
