Correct me if I’m wrong please, but this is a mobile Wallet app, an enclave, for government issued documents: Ausweis, Diploma, etc. How does a card reader come into the workflow here? I don’t quite get your point.

Currently, the card reader is the only thing that allows me to do banking and use government services on Linux. If at some point, governmental services decide to drop support for the physical-card-plus-reader systems and move everything to mobile wallets instead (like many banks already did), then I can’t do shit anymore without Apple or Google.
