If this comes from Wero as they claim, I guess we Europeans in countries that are covered by Wero are in for a bad time. That said, some Dutch banks also made the migration from iDEAL to Wero and don't require Play Integrity.
That's their "Phase 1". They are currently building new infra. My ASN bank app just yesterday actually wanted me to go through some reauthentication flow for migrating to Wero so maybe they are actually moving to that now.
