France, Germany, Sweden, Estonia and India already have government id.

I don't know what I think, I lack sufficient knowledge to have an opinion. But I still know approximately 10,000x more about UK politics, economics and immigration than 99% of the people commenting here.
France Identité app is closed source, requires GMS and Play Integrity, and is only available on closed stores. It is not yet mandatory but who knows when it'll happen. No thanks.
