EDIT: If you're looking for a press release from the Kremlin, no, I'm unlikely to be able to get something official from Vlad, only public news sources.

The existence of these alternatives is one reason Russia probably won't be banned from SWIFT in the first place.

Are there any downsides to making a payment through СПФС rather than SWIFT? For example, are you revealing information to the ФСБ, or exposing yourself to counterparty risk from the Russian government, or making it possible for the Russian government to cut you off from your payees if they want to level economic sanctions against you? A potential upside of Bitcoin in this sort of situation is that it's neutral: nobody can cut off your access to it, everybody can see your transactions (but without names and places), and you're only exposed to counterparty risk for the few minutes until your transaction is confirmed.
But, again, I don't think that'll happen in the next couple of years, and possibly never.
The tech doesn't change the policy or the law, but it does change their consequences in the real world. Fortunately it is not yet the case that the US shells every country whose citizens do business with entities it imposes sanctions on, although the US does shell a lot of countries, and it can be challenging to identify even which country a Bitcoin transaction originates from.
What's your source for "Russia is exploring crypto for transfers if they get knocked off of SWIFT"? I assume you mean cryptocurrencies of some kind, because obviously SWIFT, СПФС, and CIPS all use cryptography, so that would be too obvious to mention. Right now I think Bitcoin is the only cryptocurrency with enough trading volume to handle Russia's foreign exchange needs; I don't think that's likely to happen in the next two years, though, if it ever happens at all.
If it did happen, though, it would put an end to the concerns that Bitcoin could collapse at any moment like a Ponzi scheme.
